Hi Folks, sorry for the post but I'm stumped and I don't know where else to turn.

Here's a few pictures of the drive shaft rear end.

First off you can see there's welded tabs over the bearing caps, no sign of any c-clips/retainers.

Secondly how do you remove the unit to change the oil seal as there's no bolts retaining the bearings.

Any pictures of what they are supposed to look like or how to service this unit with or without the welded tabs would be much appreciated.

Service manual no help, as the diagram looks like it shows a bolted affair.

It looks like someone has gotten creative with your rear yolk/u-joint.

Hopefully someone will be along with a helpful answer.

Hello Bjorn,

The 1954 Chrysler products used a system that retained the cross and bushings in the yokes using snap rings. Attached is a diagram from the 1954 Chrysler Corporation parts book that shows a typical installation.

The parts book also lists the service parts for this installation individually, but also as a service kit. I believe it would be MOPAR Part number 1450 445.

I am guessing Chrysler discontinued this kit in the early 1960's but you might find an NOS kit somewhere. More likely would be finding one of the numerous aftermarket kits made for this application that should include the same parts. To repair it, you will have to grind off the tabs and remove the bushings from the cross to remove the driveshaft. Once the driveshaft is removed the pinion yoke nut will become accessible to service the pinion seal.

Good luck, that 1954 Desoto is a fine machine!
