I posted a thread on this subject a few days ago, and got several responses to the effect that I needed to shim the transmission down to reduce the angle of the u joint. Today I installed four 1/4" shims between the frame and the transmission mount and then test drove the car. There was a big difference. The vibration can only be detected in a narrow speed range around 30 MPH. Above 35-40 it disappears altogether. I'm guessing a bit at the actual speed because my speedometer reads high. I need to change the gear, but that hasn't worked it's way up to the top of the pile yet. The remaining vibration seems to be most noticeable when accelerating. Question: Should I attempt to shim the transmission down another 1/8 or 1/16?
Any additional advise would be appreciated.
