CHEVY AXLE SHAFT BEARING REMOVAL

2002 Chevrolet Trailblazer

Drive Train Axles Bearings problem
2002 Chevy Trailblazer 6 cyl Four Wheel Drive Automatic 97,000 miles

Is there a lock/clip inside the differential that has to be removed to pull the axle out and replace bearing?

No. Follow these instructions. I might add if you need help with the axle, you might want to reconsider doing this project, dAMAGING THESE SURFACES WILL COST FAR MOR THAN THE BEARING. AXLE SHAFTS -2002 Chevrolet TrailBlazer

I'm sorry Merlin, I guess I didn't specify which differential.
My question is for the rear drive axles.

In that case, at the rear, remove the cover, and pray it's not a limited slip(posi) unit. If not, you will see the ring gear and carrier, rotate it until you find the small bolt with the 5/16th head and remove it, slide out the center pin, after it's out DO NOT spin either wheel, push the axle inward at the wheel end, the clip can be rmoved now, if it doesnt fall out, then slide the axle out, use a slide hammer with the propper side bearing remover and remove the bearind.
