Pinion angle help.

Treblig said

Did you try this method while you were out on the road??
If there is no vibration under normal operating conditions then the angles are correct.
If there is vibration under acceleration, you need to add more downward pinion angle preload. If the opposite occurs, the vibrations tends to decrease or disappear under acceleration, you need to reduce the downward angle preload.

This way you know which way to go.

I hear what your saying Treblig. the noise was at any speed, while accelerating . example- While doing 45mph, coasting no noise, if you press on gas pedal ,even just enough to stay at 45 noise, and pretty loud. I have a blt 360 with dual 3in exhaust that dumps right in front of rear end. and the pinion angle was at 3 degrees nose down.
