This little problem is getting worse and worse. When Im on the highway and decelerate I get a short but hard vibrating from what feels like the rear of the car?? I dont get it while acelerating or drifting. And its only for a couple seconds. Any ideas guys?

 

check ur drive shaft bolts at the rear end. Sounds like they're loose. Or its a rear U-joint. Reach up under the car and see how much play you have in your drive shaft, if its really loose. Replace your U joints.

 

Will do thanks!
