Title: New rear control arms
Post by: russ austin on August 12, 2017, 04:51:46 PM
Dan made up some rear lower control arms and I am testing them out on my 63.  59-64 are the same control arm, so a lot of cars can possibly benefit from these.

Made stronger than the originals, and using urethane bushings made for a truck, these are made better than the stock pieces.

To start with, I have new springs and shocks on the rear. The original bushings are in the control links.
I had a local garage installed them, and the initial test drive was pure amazement to say the least.  The rear end sat up just a touch higher, eliminating the Cadillac saggy rear.  The Cadillac floating rear end is no longer there, acceleration, braking are crisper, and the driveline vibration at 50 is no longer there.

The new urethane bushings correctly position the pinion yolk, which directly effects the drive line angle. Why not just put in new bushings, as they are available?  To put it simply, they are junk, and do not last.  Dan had his new bushings in for 2 years, and they had failed.  These will last the life of the car.

For the price of 4 new bushings from OPGI, you should be able to get 2 new lower control arms with new bushings.

Once I am finished testing these out, the final price and where to get them will be available.

If your interested in possibly getting a set, let us know.  Dan will be the guy making them.

That looks fantastic! I would love to install a pair of these on my car. Please put me down for a set as soon as they are available!

Can't wait to have a true bit of McNarry ingenuity in my caddy :-)

Now when are you going to build tubular arms to replace the front upper and lowers? ;-)

Post by: 62 Coupe on August 14, 2017, 05:31:15 PM
Here are some more photos to give you an idea how the control arms are built and how strong they are. The prototypes are made from .188" (3/16") thick 2 x 3" rectangular tubing but are serious overkill. I have crunched the numbers using a tubing deflection calculator and believe that .125" would be lots strong enough but save a little weight. These ones come in at around 14 lbs each.

There are no welds perpendicular to the arms, all welds are longitudinal with the arm except the bushing sleeves and spring indexing stubs. The bushing sleeves are seamless DOM tubing so they won't prematurely wear out the urethane bushings with a rough inner seam. The spring pad is .125" as are the braces.

As Russ points out, the bushings are universal truck leave spring eye units and very tough. The front and rears are the same size for simplicity's sake.

Being prototypes, Russ's arms are very time consuming and entirely built by hand. The biggest challenge was making them identical lengths as the hole saw has a tendancy to walk a bit even though I am using a high quality Bosch unit. I have a quote from the machine shop I use for my projects and will have them CNC end mill the hole locations and the "salami" cut on the front lower end.

It looks simple enough but there is actually a lot of running around, picking up materials and cutting pieces etc besides welding, fabrication and painting. Almost forgot to mention what a pain the spring indexing stub is to make. It is the sort of tear drop shaped bit on top of the pad.

My goal is to be able to manufacture 10 sets to start based on interest. Because of the limited number costs are pretty high for me so  I would be looking for $385 USD per pair ready to bolt on, bushing included.

Wow, this looks perfect - exactly the way they should have come from the factory. Put me down for a pair. The price sounds very reasonable given the benefits and the workmanship involved.

Thank you!

awesome job Dan

a note for those of you installing them,or any bushing for that matter,make sure car is at ride height before you tighten them in place!
or you will destroy the bushings when the car is lowered back on the ground

Title: Re: New rear control arms
Post by: russ austin on August 15, 2017, 05:35:12 PM
Given the price of 4 new bushings for the rear control arm, the new control arms are just a few bucks more.
Title: Re: New rear control arms
Post by: 62 Coupe on August 15, 2017, 06:49:51 PM
The inner sleeve on urethane bushings is not bonded to the urethane so they can be installed in any position unlike bonded rubber bushings.

Peter, I will post on the modified forum as well and hopefully we can reach 10 sets spoken for.

Russ, an additional benefit is structural integrity. We should see if Cattle Ax still has a photo of his failed stock trailing arm.

There is going to have to be a grandfather clause fee on these new control arms. These new parts are making my old parts look bad.  Who wants to buy good used control arms for half off?
Title: Re: New rear control arms
Post by: russ austin on August 18, 2017, 06:52:13 PM
After a full week of testing my car, I am convinced that these new control arms are the next best thing since sliced bread.

No complaints, just improvements I'm all aspects of the car. Braking, handling, acceleration, cruising.   The back of the car sat up just a bit higher, leveling off the car. The Cadillac float and sag of the rear end is gone. A true pleasure to drive.

Get these through Dan.

Quick question: if the rear sits higher than stock couldn't you just shorten the spring support platform by 1/2" or so to get stock ride height? It seems it wouldn't affect the other benefits at all?

I can't wait to get my hands on a pair of these :)
Title: Re: New rear control arms
Post by: 62 Coupe on August 20, 2017, 07:19:37 PM
I don't believe that the new trailing arms raise the height of the car above stock ride height. The aftermarket bushings seem to have softer rubber in them than the original bushings. See the distortion of the replacement bushing in the photo below. That's a 2 year old bushing. Mind you, it was better than the old original bushing but not by much.

By 1965, Cadillac moved the coil spring from the trailing arm to the diff housing which solved the problem of loading the weight of the car through the trailing arm bushings.

Post by: Peter.1961 on August 21, 2017, 05:03:08 PM
Wow .... Interesting. I don't think my old ones looked that far off.

Out of curiosity, where did you buy those old aftermarket bushings? Mine came from rare parts, and I have seen much cheaper ones on rockauto and eBay.

The bushings are all sourced from one manufacturer. Guess what, it is an oversea's manufacturer. Junk is junk, and this is what we are having to do in order to get our cars back in tip top shape.

Post by: russ austin on August 25, 2017, 05:13:56 PM
I finally got a full load of passengers in the ol car today.  4 men in the car, and the car drove fantastic. the rear did not sag down, and over bumps, the rear did not do the traditional bob up and down.

Post by: 62 Coupe on August 25, 2017, 08:14:38 PM
Awesome! I fully load my trunk a couple of times a year going to shows that are mini vacations with the family. That's Barb, myself and two teenage daughters. The upcoming show in Radium this September is a real test. We rent a place that has a full kitchen etc. so besides all the girl stuff there is a couple of coolers of food. Max load for sure. The difference when doing the long winding decent into Radium is a night and day contrast with the better rear bushings.

I'm glad to hear the urethane bushings are working out as expected.
Title: Re: New rear control arms
Post by: Peter.1961 on August 29, 2017, 05:15:14 AM
I am very much looking forward to that!

My caddy does get its share of exercise (say five adults of my stature (call it 1000 lbs total) or the occasional trip to the hardware store when stuff is too big for our wagon. 30 cu ft of planting soil, a dozen 4x8 sheets of plywood ... You name it :-))
Title: Re: New rear control arms
Post by: 62 Coupe on August 29, 2017, 12:31:31 PM
I ordered the plates that make up the spring perches today plus the small plates that the emergency brake cable attaches to. They will be water jetted out of 10 gauge steel which is .1345", a little thicker than the prototype perches but I will make them slightly smaller as the water jet gives much more flexibility in design as manufacturing is not labor intensive and allows for greater creativity. I will still have to make the tubes themselves and cut and machine the bushing sleeves as their price is still too high for the small initial batch. I will be staying with .188" wall tubing just for the extra safety factor. It may be overkill but as all of the stress and load calculators I have tried tell me .125" is enough, I still want to err on the side of caution. A couple of pounds per set is not worth the worry.

Delivery time on the water jetted parts is 2 weeks so I expect I should be able to get some completed sets out the door in 3 weeks for those who have expressed an interest here and privately. Also of note, I am currently making a set without spring perches for one of the modified forum members. He will be grafting air bag perches on to the bare trailing arms.

I will keep you posted.

Post by: themotherbrain on August 29, 2017, 02:44:21 PM
Yeah Dan if you do a set of airbag ones I'd consider it too. I think these would suit my need. All you have to do is weld up a round plate (not near the car to measure how big the plates on mine are) in the spot where the perch would go normally. Drill a hole through the center and through the arm so you can bolt the bag in from the bottom. Easy as pie. It's nice of you offer these up.
Title: Re: New rear control arms
Post by: 62 Coupe on August 29, 2017, 04:40:53 PM
TMB, I think there are quite a few different air bag options out there, which one are you using?. Are you saying you would want them with the plate manufactured and installed? Or, would you be adapting your own plate?
Title: Re: New rear control arms
Post by: themotherbrain on August 30, 2017, 02:12:42 PM
It doesn't really matter what setup you use as they are pretty much the same lower mount for the rear. The more I think about it, the flex in my stock arms are likely more beneficial for side to side motion. I would probably need some sort of heim joint in order to not twist things up. Might be more bs than its worth to you. There is a really sweet rear tubular arm kit available on ebay but damn its expensive! I really like their front arm kit too as it eliminates the strut rod. Im never gonna fin8sh this thing at this rate!   :o
Title: Re: New rear control arms
Post by: 62 Coupe on August 30, 2017, 05:10:10 PM
If you are operating the corners individually you might want the Currie Johnnie Joints similar to what I installed on my personal custom arms. Mine are serious over kill but if you went a little narrower and made spacers for each side of the JJ inner sleeve to Caddy mounting bracket, you would have lot's of articulation.

Title: Re: New rear control arms

Hey Motherbrain, whats this about a kit elimination the strut rods? 
Title: Re: New rear control arms
Post by: 62droptop on August 30, 2017, 07:05:44 PM
speaking of rear bushings, I replaced mine with rare parts ones ,not sure how well they are holding up though

I think the biggest difference in my car handling since I boxed my arms is the fact that  the upper a arm on my rear axle  is off a 59 0r 60 and has much smaller bushings

I know boxing my stock arms made a big difference, I bet Dans arms  make a huge difference

Holy crap batman!, that's what I have been wanting to do for a while now. Get rid of the crappy bushings at the front cross member and put in a heim joint.

I sent them a message, if they made a lower control arm for the stock setup.
Title: Re: New rear control arms
Post by: 62 Coupe on August 30, 2017, 09:21:21 PM
It would be nice to know if they can supply it without the bag perches and shock mount. I'd add my own mounts to run QA1 or equivalent coil overs.
Title: Re: New rear control arms

Been messaging the guy, and they do not have lower control arms for the stock setup with springs.

Here is a photo of some arms I shipped out today for a bagged 59 project. This is the last set that I will manufacture entirely myself, the next 10 are going to have CNC machined tubes and water jetted perch components. I should have the first batch built in 2 to 3 weeks.

Post by: 62 Coupe on September 07, 2017, 03:44:25 PM
I have started making all of the bits that are not being done at the machine shop. So far I have found a good method for making the spring pad indexing/locating ring and am currently making the bushing outer sleeves that get welded in to the control arm tubes. It's a bit tedious but I just can't afford the machine shop rates for something I can do myself. So far I have 20 sleeves faced to length so that covers the 5 sets that are spoken for but while I am set up, I'll do 20 more to make a total of 40 for 10 control arm sets I have coming from the machine shop. After I face the 40 sleeves I need to put them all back in again and machine the inner chamfer.

I'm using the steady rest because my lathe is so small the chuck jaws aren't big enough to support the sleeves safely. The double wall shipping boxes have been ordered as have all the remaining spring perch parts and control arm tubes.

The urethane bushing arrived for the first 10 sets and I am hoping to have everything else sometime next week.

There is a US Postal Service outpost here in town that can handle all of the brokerage and shipping for guys in the US. With the made to order boxes, the packaging size has been reduced which means the rate to Arizona is now $32. I have a quote to New York for $36. This gives you some idea of what shipping fees will be.

To those on the order list, thanks for your patience.

Thanks guys. The machine shop called today letting me know the parts were ready so I took the shop truck over and picked them up. Three hundred pounds behind the axle barely made the old gal squat. I will continue making the small bits then should get on to welding some up later next week.

I finished the sleeves for ten sets of trailing arms this morning. I forgot what a busy day I have scheduled for today and tomorrow. I need to go up to meet my daughter at her college this afternoon and buy her books and supplies then over to pick up the boxes for the trailing arms and another length of 2 x 3" for making the perch risers. Tomorrow afternoon it's off to get a hair cut and appear at a good friends post wedding dinner. On top of all that I want to give Carmen a good look over before heading out to Radium on Friday. I have put a ton of miles on her this year and don't want to neglect anything before her last longish trip this year. I may not get any sets welded up this week but will certainly be in position to begin next Monday.

Post by: AutoCad on September 12, 2017, 07:30:44 AM
Looking good, Dan! And now I'm wondering...while I'm installing your new lower control arms in my SDV, would this not be a good time to look at the rear upper control arm?? I see that the upper ball joint (RP10450) is available, as are replacement rubber bushings. Do you have some improvement in mind for them as well, is there an upgraded poly bushing that could be subbed, or is it even necessary?? Are we only addressing 1/2 the problem here I wonder?? Your thoughts??
Title: Re: New rear control arms
Post by: 62 Coupe on September 12, 2017, 09:40:48 AM
The upper bushings aren't as critical as the lower rear bushings as they carry no weight. They do control the lateral location of the diff and the fore-aft motion of the top of the diff. I talked to a race car guy I know who is really good at chassis set up and suspension. He pit crews on the vintage racing circuit looking after a really hairy Corvette and has forgotten more than I will ever know. He says that the fore-aft control of the upper yoke is a fraction of the stress placed on the lower control arms in both acceleration and decel. So, in terms of inducing drive train vibration there is likely little gain in changing the upper bushings if the current ones are in good shape. The spherical joint is a real safety issue if it fails and if in doubt should be changed pronto.

Russ Austin has a spare upper control arm he is willing to give me and I have a notion to build replacement yokes using Johnnie Joints instead of bushings. This could be screwed in and out differentialy to move the rear axle side to side a bit to help with lateral alignment. It would also provide an opportunity to change to a more common spherical joint that is not so expensive to replace.

All in all, the biggest bang for your buck is in getting the soft rubber out of the lower rear control arms.
Title: Re: New rear control arms
Post by: AutoCad on September 12, 2017, 10:04:06 AM
Sounds well informed to me, Dan. That upper ball joint is kinda spendy, (around $120.00 USD from what I can find), but better to change it out when you want to, rather than when you have to, I say. Great info as usual. Thanks alot.  KenO

Title: Re: New rear control arms
Post by: 62 Coupe on September 13, 2017, 09:20:50 AM
If you are wondering what is involved in changing out the spherical joint, it isn't too difficult. If you support the rear of the car on jack stands and use a floor jack to control the height of the diff you can proceed as follows;

1) With the rear tires off the ground, use suitable jack stands to support the car ahead of rear axle. (I use heavy duty 6 ton stands)
2) Jack the diff up 4 inches or so and support each end with a small jack stand
3) Take out the split pin in the rear spherical joint and losen the nut
4) Using a heavy hammer, hit the diff lug until the joint releases (if the joint won't release, take the nut off and turn it over so the castilations are up then try hammering it up with every second or third blow)
5) When the joint comes free, remove the nut and take the two upper bushing bolts out
6) Remove the upper yoke out and over the back of the diff. You may have to drop the diff slightly if it is too high
7) If there are rivets holding the spherical joint to the control yoke, it has never been removed. I have had good luck flattening the head of the rivet with an angle grinder then a centre punch and drill. Just drill enough to take the head of the rivet off then push the rivet through with a pin punch.
8) Assemble the spherical joint and control yoke then reverse the above procedure but with a twist, make sure to support the car by the rear diff with jack stands to replicate ride height before tightening the front control yoke bolts..

Title: Re: New rear control arms
Post by: Peter.1961 on September 13, 2017, 05:32:26 PM
My spherical joint gave out under load (was doing a fast left turn into a busy street and inducing a fair bit of on-power oversteer) -- not a fun experience (the joint giving out.  The oversteer is always fun :-)).

I was fortunate and all I lost in the process was a fender skirt (the axle moved sideways, pushed it out, and it flew about 20 feet in the air and landed 100 feet down the road - and a truck ran it over before I could get it).  The body prevented the axle from moving more so I did not incur any further damage to the drive line etc.

Only one out of three times I had to get the caddy towed in 45k miles.

Definitely worthwhile replacing while you have the chance.
Title: Re: New rear control arms
Post by: 62 Coupe on September 13, 2017, 05:57:11 PM
I forgot to mention that the bushing bolts should be tightened with the car at ride height. You can support the car with jack stands under the diff ends to get approximate ride height. It doesn't matter with the urethane equipped replacement control arms. The inner sleeve rotates in the bushing. I'll edit the previous post.

Hi Russ,
Are you referring to the rear control arms discussed in this thread?
When strut rod is mentioned, I think of the front end and the long rods that connect from the wheel to the front cross member under the radiator.
Which are you referring to?

I got out in the garage today and made the risers and spring locators for the first 3 sets. I spent a bit of time making jigs too so that I can make the parts a little faster. I fully expect that I will have all of the spoken for trailing arms done this week and may even get all 10 sets built.

I left the spring locator open on one end to allow water and muck drain out.

Hi. 
Can the future members installing these rear control arms; please measure the before-and-after rear differential flange distance to the pavement , or its aiming angle ?
Miguel
Title: Re: New rear control arms
Post by: 62 Coupe on September 23, 2017, 09:07:03 PM
Miguel, They are the stock length so they shouldn't change pinion angle much if at all. What they do is centre the rear trailing arm bolt in the control arm by taking the sag out of the soft rubber bushing. That raises the car to a more normal ride height if the bushings are bad or soft. Being urethane, they control the forward and aft motion of the lower diff to trailing arm pivot which in turns stops the pinion from changing angles excessively under load or braking.
Title: Re: New rear control arms
Post by: Externet on September 24, 2017, 09:36:21 AM
Thank you.
Yes, correct.  The minor raise in rear height comes from the now-centered new bushings instead of the sagged/deformed old ones.
I would like to confirm such minor raise is also shown with a minor elevation of the differential input flange.

My cars have (had) shims in front of the front bracket that holds the front ends of the control arms.  When removed, height raised and the pumpkin did too.
The removal of those shims compensated in a wrong way to do it, the shifting of the bushings center hole position by rubber deformation.

The pumpkin angle changes also with the load placed at the rear of the car.   Pushing the rear down by hand, the pumpkin angle raises.  Also in uneven pavement, as sags/swells in the road, changes the angle accordingly.

Off-centered bushings also place a considerable sheer force to the central ball joint by changing the correct control arms length.

Hello Dan!! Just received my new control arms today, and the first adjective that came to my mind was "MASSIVE!!!".  Holy cow, at about 20lbs each, they are very well made. Your design and fabrication skills are second to no one, sir.  Just awesome, thank you.  KenO

Ken, they are about 30% heavier than stock but much stronger and have good bushings. I'm sure you will enjoy the improved stability they provide.

I got them on Friday -- they look fantastic!  Unfortunately I'm out of the country for a business trip for the rest of the week so I don't get to play with them :-(

Thank you, Dan!
