I got rid of most of the vibration that's plagued many of us with frame mounted TAs.

As many of you, I've changed my pinion angle dozens of times. Here's what I did the last time to make it work:

I removed the DS and measured the transmission output shaft = 5 degrees down from front to back.

I then installed the DS and measeured the the axle angle off of the bottom plate of the torque arm where it bolts to the axle. (If I do it again, I would measure the actual pinion angle)

I set the axle at +3.5 facing up towards the front of the car.

I now have less than 2 degrees defference between the 2.

Some people insist that the pinion needs to be 2 degrees down but I've read up alot on this and it applies to leaf spring set ups due to the flex on the front of the leaf on acceleration.

yes... the pinion angledoesn't need to be anything other than 0 unless you're really doing some very hard launches

The 0 to -2 pinion angle should be relative to the crank centerline--not the ground. Measure the angle on the face of the crank pulley. Measure the pinion across the yoke and set it 0-2 down from the crank pulley.
