Re: Noisey shock or rear axel?
Shock bolts are the easiest thing to check first. The uppers tend to rattle because the shoulder of the bolt isn't thick enough. I got replacement higher grade bolts for mine from my local Fastenal and torqued the hell out of them. I was getting a "thunk" noise everytime I hit a bump. The ball joint at the top of the rear 3 link is notorious for failing too...and while you're under there, check the sway bushings and make sure all the bolts are snug.
