whenever i stomp on the gas, in between 3/4000 rpm the rear end shakes like crazy. any ideas what this could be? just a U joint issue or whole driveshaft? any help appreciated.

carrier bearing, subframe bushings, cv shafts, wheel bearings, tie rod ends, lots of possible causes

I've also heard of something like this coming from a malfunctioning HICAS system, assuming yours is a TT. you'll just have to narrow it down.

mines a N/A. Im assuming its somewhere in the drive shaft wether it be a U joint or the bearing. I just wanted to know if anyone else had similiar problems.

Shifted belt in a tire, loose wheel maybe a wheel out of balance.......bent axles.....etc. Could be a lot of stuff.

the carrier bearing is by far the most common problem, but there is no replacment for getting under the car and inspecting the condition of all the parts

Mine does a wheel hop type of thing when i get on it going around left corners. It's pretty violent. I've done a lot of reading trying to find something similar and it pointed to shocks. I haven't replaced them yet because the car drives fine otherwise. It's on my "to do" list though.

when the rear shocks go it've very noticible ont he interstate when you hit an expansion joint or other bump, the back kinda skisp around, severs wheel hop when taking off is a sign of subframe bushings
