Title: Changing upper ball joint
Post by: Ramses on June 05, 2018, 08:43:12 PM
Hi all!

  i want to install my new upper ball joint on my 1962, but the one i received dont look identical at the one i have on the control arm..

picture 1 & 2: look at the size of the shaft, the new one is smaller than the old one

Picture 3: The new ball joint have a metal plate at the bottom but the old one on the arm dont have that,,


i dont figure out how to use that, maybe i have received a wrong upper joint? or maybe someone can help me to figure how to install that?

thanks for your help :)

The difference in the shaft size is the concentric cam the is on the old one . It needs to be taken off and put on the new one. This is used to align the front end.

There is a left and right upper ball joint. That one in the picture looks like one of them. Do you have a service Manuel?

thanks for your answer..


Yes i have a manual,

So ok, i can try to remove the shaft and put it on the new joint.. that make sense.. (i have look at my manual and picture fig.4-8 show that)

Actualy in the manual, they talk about replacing the seal on the upper ball joint (fig 4-27) but they dont explain how to replace the joint itself... And i dont figure out what to do with the metal plate (picture 3 on my first post) maybe i have to remove that plate and dont use it?

the  new upper ball joint you have is not for a 62 caddy.the cam is not removable . the new ball joint will look exactly like the one you have in your car.the cam and adjusting nut are one piece and part of the whole joint.it has to be solid as to make an alighnment corrections.

ok, but when i do a search on EBAY, for "1962 cadillac upper joint", all the joint that i see are exactly like the new one i have.. there is no other upper joint ...

after looking at the manual i realized that the size of the shaft is the same, the difference is because my old one have a part called "camber exentric" over the shaft.. (manual figure 4-8, 4-9, 4-10) so i do not have to replace the shaft itself, juste the part over it..

But that dosent fix the problem of the metal part at the bottom

The old one actually welded on  You will need to cut the weld.
The new one clamps into the hole.  That ring is a threaded lock collar.
They are different right to left.  look for that under the rubber boot.

Thank you for the compliment and good luck.   

I am having a lot of fun on all of these steps and I love it when I can help others in some way.

Getting the camber eccentric off can be a real pain. I tried it with a puller and promptly broke the jar of my trusty snap on puller.

I ended up using a 10 ton press (supporting the bottom of the eccentric and pushing down on the shaft) - and needed more than 5 tons to pop it off.

5 tons!! i dont have a 10 tons press here.. I will have to visit my local machine shop to get them removed!

i have seen new and used one on ebay too.. so if its too mutch problem i know where to found other camber eccentric..

By the way, when its removed, does it have to be pressed on the new ball joint??

I used a lot of heat to get mine off. It kind of sets itself when you install it. It is supposed to be able to rotate.

The irony is, I ended up replacing mine with new ones from rareparts ... They looked a bit worn so I figured might as well ...

It does set itself when you install it and tighten the nut. It's the beauty of a cone - easy to mate, very hard to separate.

I think when you rotate them for alignment you rotate the eccentric with the shaft as a unit. (Rotate the shaft in the ball joint)?

i have try to rotate my old one, and that camber exentric dosent rotate on the shaft, but the shaft rotate easily..

I am actually sandblasting my old arm, when its done i will bring them to my local machine shop because i dont have a press here

I finally have the new front upper ball joint installed.. There is a plate under it, so it does not look exactly like the original, but i have installed it easily :)



Thanks to those who help me with that :)

Hi all,

maybe a bit late to the discussion, but may help others.

To remove the camber eccentric bush the easiest way is to just cut the old ball joint shaft just below the bush with a thin grinder blade on an angle grinder, the ball joint is toast anyway so just cut it.

The bush can then be easily supported on a regular press bed on a socket, or a nut large enough for the shaft to go into, then press it off, the come off very easy like this.

I did mine in a large bench vice. If you added a small amount of heat they would be off in seconds.
