why does my rear end shake at freeway speeds.and it also makes a clicking-clunicking noise when i slow down from 10 mph to 0 mph when im in neatral.i also had a new driveshaft just put in. i have 45k miles on the rear end. the car has been pushed hard at the track a couple of times and driven hard on the streets i launch at about 7000 rpm.what do you think the problem is and what should i do about it.

 

I also have the clicking-clunckin noise when I slow down from 10mph to 0mph
Also try doing a very slow 180 degree turn in nuetral. You will hear more of the cluncking noise
Would love to know what that is or if anyone has some details

 

what do you think the problem is and what should i do about it. ??

seriously are you that much of a retard..... maybe you should fix it, in fact try going to a mechanic genius. On second thought just keep driving it and tell us what happens But if i was to guess cause i am a mechanic i would say its your diff or axles... i cant truly tell you cause i would have to hear it and look at it. So go to a mechanic, and i would definatly not drive the car anymore if its shaking at highway speeds cause that means that something is really wrong......
