Replacing axle bearings

Just wondering with the G80 is there any tricks to removing the C-clip for the axle as opposed to a standard diff?

I just don't want it to fall somewhere I cannot retrieve it, I assume it will fall to the diff housing.

Also, what bearings/seals have been used with success?

Thanks.

I don't have a G80 in my TB, but I do on my GMC pickup. There is a lot less room to pull the c-clips out- I used one of those telescoping magnetic pickup tools to pull the clips out. I imagine any of the GM G80's are the same.

Hope that helps.

They both are close in the amount of space for the c clips if you have some hemostats that what I use to pull them out and put them back in

Replacing the axle bearing was one of the first things I did when I bought my TB. I don't remember which one I got, but I do know that it has lasted 70,000 miles.

There's a good thread on the OS about an axle bearing replacement. Rear Axle Bearing Replacement -- Illustrated - Chevy TrailBlazer, TrailBlazer SS and GMC Envoy Forum

The process is tricky, since you have to get the pinion shaft partially out of the way, and there's a retention bolt used as a setscrew to keep it in place. The OS thread is a regular carrier - here's a picture of my G80.

I did see that thread, thanks for the link. Looks much more crowded inside the G80 though. Will a magnet still pull the clip?

What about bearings....any particular to avoid?

Magnet or pick. It has to be possible, because people have done it. Take pictures, so you can post for helping future members.

Don't recall anybody putting in bearings that had to be replaced again, so we don't have any history. Not even on the OS.
