Need some help A.S.A.P.
Anyways I think it might be the rear-end finally, what is the best upgrade I can get for daily driving/dragracing and how much $$$ am I looking at?
I think it also might be due to my new driveshaft not being balanced right when it was installed (but thats been like... 2,000 miles ago, would it still effect it?)
I need to know something quick before I take it down to the dealership and start ordering things, wish this was a H/C I was ordering
