    4x4 rear axle shaft bearing and seals.

    So I finally got around to the rear axle seal seep on my Ram 50. Pulled the drum brakes apart, pulled the axle out, pulled the locknut off and lock washer but now I can’t, for the life of me, get the bearing off. I can’t find any information on this process anywhere on the web. Everything is for 2wd or for a totally different axle. Common sense says that it’s not pressed on, otherwise why would it have a threaded axle nut to set the preload.

    I’ve got it suspended with blocks of wood and have been smacking the splined end with a wood block and a hammer. While this has resulted in the bearing moving a 1/4” of distance down the axle, it’s not budging at all now that it’s right at the threaded section.

    Do I just need to get this in a press to finish getting the bearing off? Does a more knowledgeable person the craft of mighty max wrenching have more wisdom to impart?

    Here's a link to pages out of the factory manual on servicing the rear hubs. It references a special tool, MB990787-A, for removing the axle shaft and bearing from the bearing case.

    However, look at this thread. The member is doing the same thing as you and has some helpful observations and suggestions:

    Wow….just wow. After reading that post Im glad I’m not the only one who thinks this is the craziest wheel bearing setup ever. Time to find some steel and start drilling I guess. Certainly don’t wanna pay $150 for a tool I’m only going to use twice lol.

    It makes sense how to remove it after seeing the tool and reading the procedure, still though, who thought to engineer it this way!

    Thanks for the guidance FMS88!

    Does anyone here have a plate already fabbed that they’d like to sell me, lol?
