Got to agree with Lou about the date, it is definately no later than 57 just from the clothes and hairstyles in the photos. I reckon 56 is favourite as a 2 year old car for Miss America 1957 might not have been good enough ! Phil

Nice job Dan as always.
I posted a write up on the rear spherical joint a while back.
Should be able to find in the search function.

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

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.

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??

Thanks for that info, Pat!!! My new axle seals just showed up in the mail yesterday, so it looks like my Saturday is all planned out.

I woud not worry. However, if you do, try to sand one of those marks and see if it's deep. I overhauled about 20 such transmissions, never had a doubt about the bellhousing.
