The latest on the vibration.....
I finally got things set up to check the pinion angle. As suspected it was way off. Or what I should say is pinion to transmission angle is way off. Pinion agle is sitting 1 degree positive (pointing slightly up). Tranny output shaft is pointing 6 degrees positive (pointing down). So I have a 7 degree problem! Plus the engine angle is bad at 4-5 degrees (pointing same way as tranny. So, I am fabricating a new tranny crossmember. I believe if I level the engine I will straighten out the tranny angle. I tried this when I was measuring the angle using a jack and I can get the angle of the tranny out shaft within 2-3 degrees positive (pointing down) without causing any reengineering of the motor mounts or drive line cowling.
However, I would like to get the pinion angle 2-3 degrees negative (pointing down) and I don't see any way of doing it with the rear suspension setup. The upper and lower control arms and sway bar looks like they lock the angle in. It seems like I would have to do some "major" suspension changes to get a negative pinion angle. I have read that the negative pinion angle is not as much of a problem with my suspension setup. It does matter a bunch when you are running leaf springs but then a few spacers and you problem is solved.
Any ideas on this one greatly appreciated.
