Okay I'm sure this has been covered somewhere but I can't find anything. I have a welded 4.10 differential and the right bearing seized up on me completely. What will be needed to put new bearings in it? I already took it out

The hardest part is getting the races and cones off- you need a puller that can get on the
lip, and that's not easy. Or cut them off- that always makes me nervous, so go carefully.
Then a press to put the new ones in.
It's been a long time since I did a mid- case- I forget the details- or rather, I'm afraid I'm
mixing up generations of diff.
Take it apart. Keep the spacers in their original locations, and you should be able to figure it out.
tnow, sometimes I just mess with people. It's more entertaining that way. george graves

Here's my question: If a bearing has "seized completely," how likely is it that the diff is comprehensively fucked? That seems like something that results in collateral damage.2006 GMC Sierra 2500HD 4WD LBZ/Allison

Yeah, I agree, if the bearings died a natural (or unnatural) death, the gearset shouldn't look so good.
But if by some miracle, the gears were aligned mostly correctly and the bearing preload
was too high, that'd kill the sidecase bearings and not hurt the gears.
I've revived a few "dead" diffs that had the pinion crush sleeve overcompressed-
the bearings die quickly and noisily, but usually everything else is ok.

When I hear the words bearing and welded in the same sentence I'm reminded of having some welding done in a shipyard. I was told that if you don't put the ground right near where you are welding you are very likely to arc your bearings leading to a drastically shortened life.Seat Shocks....I have passed the baton to John Christy from Ninestitch.
