I searched already and didn't find anyone with a Roush kit using shims but I have this vibration all of a sudden after the suspension went in. I haven't gotten around to getting under there to check the pinion angle (don't even know if I will fit).

Just wondering if you have had any problems and what you did to solve them? I also had the wheels rebalanced and that seemed to help a bit but not much. It seems to vibrate annoyingly around 60-65 then tapers off once 70 and up hits.

Thanks for any advice.

 

is the vibration in the seat or in the steering wheel?

I can feel it in my seat and the passenger seat (empty) shakes likes it's a vibrating lazyboy. Steering wheel used to shake before the wheel balancing but no longer doesn't.

 

yup thats in the rear. Throw in some shims and watch that vibration go away

will have to measure it and figure out what I need. What have you guys been using? 4, 6?

Thanks for the help.
