I replaced the rear seals and bearings in my '99 Suburban. When I tried to put the axles back in.... they wont go. I can get them in all way to the bearing surface and the splines engage. I whacked one of the axles to... well.... help it go in, but just managed to get it stuck. Hopefully I will deal with that issue tomorrow. I also sighted down the axle tubes and all looks good. Any ideas???

 

Well... I got the axle back out with a porta power and pulled the axle bearing. The bearing doesn't fit on the shaft, hence the wrong bearing.
Moral to the story.... check the bearing before installation.

 

good job. always size up new with old. i've learned that lesson long ago
