annoying rear noise! help
iv been thinking about replacing one of my axle shafts, both bearings, and seals. the reason is for the axle shaft, i was getting my car dyno turned and the tuner and a kid said my rear wheel was a bit wobbley while making a run. so then i had the rear of car up on jack stands and started it and put it in drive and noticed my driver side rear wheel was indeed wobbley. i slid into a curb 3 years ago and trashed my weld circle light rim on the rear, but i already replaced it...back to subject, to make sure it wasnt the wheel (the new one), i took the wheel off and put the lugs on against the rear rotor and ran it again. sure enough the axle flange is bent. so iv been looking around for axle shafts, but the cheapest NEW shaft i found was right under $200. should i get a used one?? but i dont want another worn out one or even bent one. AND another problem, im not sure if the axle bearings would cause this, but when im cruisin down the road and hit the slightest bump (and i mean SLIGHTEST) it makes a clatter noise. like a sharp "clack" or "ting". its very annoying
and very embarrasing. and to narrow it down to the axle bearings, when i had it up on jack stands, i kicked the wheel and it made that "clack" noise. so i cant be suspension components... has anyone experienced this noise or problem???

Re: annoying rear noise! help
The noise that you heard when you kicked the wheel was the axle hitting the cross shaft in the differential. The c clip has a little slack in it and it allows the axle to move in and out a little bit. It's nothgin to worry about unless the axle is moving about 1/8 inch or more.
I'm sending a PM about the axle shaft.

I'd just find a 4th gen rear end and upgrade. I bet if you look around you could get one for $250 or so pretty easy.

I like the stance with the rear wheels a little wider. Guess it's the ****** man in me trying to get out!

Re: annoying rear noise! help
you must have took me wrong... i like the deep dish rims, as in they are the same overall width as any fourth gen wheels fitting in these same wheel wells. its the back spacing differance im talking about. you can have a 10" deep dish rim (like i currently have) and it not stick out the side, and with a fourth gen rear end with fourth gen rear wheels, you cant gain MORE over all wheel width, the back spacing or offset will just be changed.... so yeah, i like WIDE rear tires too, just want that deep lip.
