1953 Ultramatic Driveshaft

Hey Guys,

I cannot find much info on this so here it goes... I'm replacing the pinion shaft seal so I figured I would replace the rear universal at the same time.

The two universal bearings on the rear axle side come out easy once the slip key is removed. The two on the drive shaft show no snap ring or lock key so I have no idea how to pull or press them out.

Can anyone help me with this? I cannot find anything in the service manual about this setup.

There is not much factory info but there are a few paragraphs in various service manuals. Here is the 51-4 info. I don't recall if there is much difference between 47 and 53 but I had no real problems in changing a 47 rear. The bearings were very tightly pressed into the yoke and the instructions saying to tap them out were somewhat optimistic though.. Is the type installed on your car not covered? If so, perhaps checking a 46-50 or 55-6 parts manual will have some into.

Hopefully you just need the rears. Front ball and trunion parts for senior Ultramatic models are non existent and several have had to resort to getting a modern slip joint type installed if theirs needed work.

If you dig a little deeper through the muck you will find that there are c-clips around the bearing caps on the inside of the yoke.

Fantastic! Clips came right off. Will soak the bearings with PB Blaster then pull those on out.
