Default What do i check??

I got a 94 Formula A4 with stock trany, driveshaft, and rear end. i recently put in some relo brackets and some comp eng drag shocks set at 50/50. When i first put the relo brackets i noticed when cruising at 50mph that there was no vibration but when trying to speed up i would get a horrible vibration from the rear passenger side. I then thought to myself that the shocks were out since they had 200,000 miles on them and then went with the comp eng drag shocks but it did not take the problem away. This only happens when i get on it after 50mph till about 60mph and the problem seems to stop. All bolts seem to be nice and tight and nothin seems to be out of order. So what do you guys suggest looking into? Thanx in advance for any help and sry for the long read

Hello,

It sounds to be like a drive line vibration or a tire out of balance. When you installed the relocation brackets did you happen to bump a weight off one of the wheels? Look at all the weight positions and see if it looks like one recently came off. An out of balance tire is notorious for this.

Hope that helps,
Ryan

I will look into it but why would it only be on acceleration from 50 to 60? If im jus lettin it coast at 50 it wont do it.
