How to change rear wheel bearing in 05 Trailblazer

I have already removed the tire caliper and rotor. Cannot figure out how to get to the bearing. Any ideas?

The rear axle bearings are not like the front, unitized, types. It's #23 in the picture below.

Short version:
You need to remove the diff cover (18), drain the fluid.
Remove the cross pin bolt (13) Pull the spider gear cross pin (14), push the axle(s) in and remove a "U" clip (36).
Pull the axle out of the housing.
Replace the seal too (24)

You are welcome, hope it works out for you.
Oh, and one more thing, he will need a slide hammer to get the old bearings out of the axle. They can be rented at most auto part stores for just a deposit.

Turns out the bearings in both wheels were fine. Our next step is to take it to the shop lol. Any ideas what would make the same sound? I guess maybe a pinion bearing sounds alot like a bad wheel bearing from what I've been told. Would really like to do the work here @ home and save a couple bucks but from what I understand about changing the pinion bearing, looks like the shop is our only option.
