Differential pinion seal replacement

As for the 11 hole carrier gasket if you want one...

All MoPar six cylinder cars except wagons and long WB cars use the same gasket. 1/2 pickup' with 11 bolt the same.

If it's a 10 bolt carrier it's the same as the 1941-50 Chrysler eight cars.

Either one

...Olson's  Gaskets here in Port Orchard Washington will have the correct one.

Count the bolt holes for the correct gasket.

I just use a good RTV sealant instead of a carrier mounting gasket. As for the seal and bearings... you can usually find identification numbers stamped into the parts that can be used by a good parts counter person to cross reference them. Or, if you have a parts book for your car you can often cross reference the OEM part number. 

I've had really good experiences with Permatex 'The Right Stuff' sealant.  Rock auto has a great part number lookup for a lot of things, including OEM numbers and xref.  All the bearing manufacturers have an online catalog that provides the ability to check numbers.  Chicago Rawhide seal info is online too. 

So much info available on the 'net, sure wish it was available when I was several, no a lot, of years younger.  I remember spending hours poring over catalogs looking for info that I can get in a few minutes from my recliner now!

Thanks. Any tips on what is going to happen when I pull this thing apart? I have never pulled a diff apart. Axles are out. I have looked at some exploded diagrams, but can't really tell what holds everything together in there. Is it difficult to get the pinion out of there? Thanks again.

Go to the DEPTCA web site and look at the Pilots Knowledge page. There you will find a copy of a B4 series shop manual. You can download the rear axle chapter and read through it. 

Here's a link to the page for you. http://dodgepilothouseclub.org/know/B4_manual/manual.htm 

 

There is also a copy of another truck repair manual that covers '49-'58 with the chapters from the Dodge section available for download. http://dodgepilothouseclub.org/know/manual/manual.htm The Rear axle chapter here may give you some other info for reference.

Thanks. I know I can get numbers off of the parts when I remove them. But, this is my daily driver. I drive an 85 d250 in the meantime. But I figure if I can get the parts on hand ahead of time, it might decrease my time off the road.

A word of caution:

I attempted to line up all of the parts to rebuild the rear axle on The Blue Bomber, and got tripped up in several ways so that instead of it being an Independence Day weekend project, it turned into frustration til after Labor Day.  Pinion bearings fit but were not exactly the same size, requiring a bearing shim kit to be ordered (2 week lead time)...did not realize the pinion seal was the wrong size, even though Chrysler said it was but Dana said NOPE; eventually, I deduced the correct part number several days later, then was told 3 week lead time.  In the meantime, the AC on the truck I borrowed blew up, so I had to stop and fix that...all while commuting to and from a job over an hour away.

 

My point is, ya might want to have a backup plan ready, cuz ol' Murphy said something about stuff going wrong all the gdtime...it happens, no sense in getting worked about it, just be prepared for alternatives to what ya originally planned.
