I recently had all four tires ballenced, had the driveline rebalenced and straightened, and I just finished properly installing a 4 degree shim on each side. The vibration has now moved to about 65/70 MPH with the instalation of the shims. I'm thinking that the shim may have changed the angle excessivly or perhaps not enough. I will return to the driveline shop today and have them measure the angle. Ill let you know my progress. Thanks for your help.

tooke me a while to reply, but I went to the driveline shop a while ago and they told me that my u joint working angle is too great, 5.1 degrees. I'm going to rais the rear of the trans .75'' and the *** end 2'' and reshim the diff to 2 degrees and se if that fixes it.

 

Sorry for the long pause in updates, but life has been a little crazy. I went to the drive ling shop and they answered my vibration problem. My working angle in 5.1 degrees. I now need to tunnel the car and raise the trans 2.21 inches to get less of a down angle on it. I'll let you all know how it goes when I finish this project. Oh and it's going to be a while before I get started so don't look for anything too soon, lol.
