I am looking for a front seal for the yoke in the rear end of the 1954 DeSoto. After the earthquake and hurricane, I found a river of axel grease flowing from the yoke. I am actually thinking about driving to Chattanooga (assuming I actually have finished my Doctorate by then). However, I have to replace that seal first. I haven't been able to locate it through Bernbaum or Roberts. Any other ideas?
Thanks,
Larry
Good to hear from you Larry!
There should be a part number that you can find on the outer flange of the old seal underneath the dirt and grease, and your parts store should be able to provide a replacement based on that number.
If you can't successfully find a part number, the parts store can get you a seal based on the dimensions of the old one. Measure the inside diameter of the pinion housing where the seal installs, and the outside dimension of the yoke (in a place that has no wear...) The seal is probably about 1/2" high.
It's also a good idea to plan for installing a speedy sleeve on the yoke. The friction of the seal on the yoke for all those years typically creates a groove that can sometimes be bad enough that a new seal doesn't even work.
Make sure the level of the gear oil is up to specs!
It's supposed to be fun!

Tim...are we talking here about what might also be called the pinion seal? If so, I have a parts book through '54 and I can research the correct MoPar p/n and perhaps find replacement stock p/n's.
The pinion seal is what I took Larry to be asking about.
My local parts store has a mixed success level on using old part numbers. Sometimes they cross reference quite easily, and sometimes they come up blank. We typically can get an old seal, bearing, or race removed without total destruction of the part and then have the part number from the existing part.
The pinion seal for the '56 Dodge we're restoring is an instance where the old number on the existing part didn't do us any good, and IIRC it was a DCDP part number. The local O'Reilly's parts store has an excellent counter staff, and we just measured the OD of the old seal, and the OD of the pinion, and ordered a new seal by dimension. And again, we installed a speedysleeve.
It's supposed to be fun!

Larry,
My '46 - '54 MoPar Parts catalog shows the oil seal for front drive pinion bearing as p/n 1327893. Searching that p/n on PartsVoice shows at least four vendors with that part in stock. Good luck! Hope to see you in Chattanooga.

Tim, where do you get the speedy sleeves from and doesn't the sleeve change the required ID of the pinion seal? Or is it real thin and does not matter? How does it get installed so it does not spin?
I had replaced this seal on my 53 and it still leaked even though less. The car really does not have enough miles to wear a groove - 30000 miles.
Mark, is the P/N good for a 53 also?
I can get speedy sleeves from both my NAPA or O'Reilly's parts store locally.
They're pretty thin walled, and don't have an impact on the seal diameter. They come with an installation tool and have an interference fit.
It's supposed to be fun!

Paul,
The same seal fits '53-'54 DeSoto. Note that the eBay link to Mitchell MoPar lists "same as Victor 47111". A good parts store can probably use that Victor number to cross to a current part number in a replacement seal.

Thank you Tim and Mark. Good info.
