Don't shoot!! Ch**y question... rear diff
I always hate to gunk up out beloved Ford forum with a Ch**y question, but I have no choice - the Ch**y forum is about worthless. As I posted on it I noticed the other two posts below mine were three days old and only one or two answers! 
Here's my post on thiers...
<!--GALLERYINCLUDE--> Howdy! My wifes' 2001 Astro rear wheel dive appears to be on it's way out. It only has 47,000 miles on it and it's making a noise like a bearing is waisted. I put it up on jack stands and it sounds like the passenger side rear bearing. My brother in law the mechanic (he's away at the grey bar motel, so no help there) tells me "don't even get started on it, it's probably an inner bearing closer to the pumpkin." Looks like the rear bearing is nicely tucked away behind a rear seal...whatta pain. Anyway can Somebody tell me how bad is it to repair? Any advice or help is appreciated!

I T H I N K them Chevalays have c-clips on the ends of the axles inside the diff housing. So, you must remove the rear cover of the diff and pull the clip(s). Then, you pull the wheel, brake and there should be some retainer nuts or bolts holding the bearing into the end of the axle tube. Once them babys are off and resting comfortably in the hubcap, you should be able to slide-hammer the axle and bearing out of the housing. Then a quick trip to the parts man to get a new one and (probably) have it pressed on to the axle. Reverse the process and drive with pride. Don't forget gaskets for the diff cover and axle end.
