Hi, I'm wondering what work is involved in changing the bits inside my rear end. The cars is a 2000 Trans-Am WS6. I need to get new axels as one side is badly pitted, thought it was the bearing until we went to change the bearing and say the damage on the shaft.

So what I want to do is replace the axels with some good ones. I've been told that I could change my rear diff at the same time for an Eaton Posi. so okay, I'll get one of those too. Was also going to get bearing kit and a rear end gasket and new cover plate.

I was going to get my local mechanic to do it as he owes me a few favours, he has been great at changing the suspension, doing the exhaust, heads and cam. But is this job something he can do? well I wants to post the question to see what's involved.

What's involved in changing the rear diff, does it need shims? or anything like that?

I'm not changing gears at this point, although could be talked into 3.90's I do a lot of highway driving around 90mph. So 4.10's would be going a little extreme. The car will still be a daily run about. I just wanted to freshen up the rear end as I have to change the axle anyway, and its done 150k miles.

Chaning the axles and the axle bearings are something really easy to do. As far as the gears, I would make sure he knows what he is doing, pattern wise, backlash etc.... cause if they are off you will have premature failure or gear noise.

Yes you will need shims if your buddy doesn't.

Thanks for the info. I'll have a word with him. We do have a local shop which specialise in rear ends, trying to save some bucks, possibly in the long run it may not save money, and may be best if I let a pro do it.
