I have clamped both sides as the leaves come together from the front hanger to the U bolts. Still shook.
When I installed the Super Stock springs I did remove the 4 degree shims I had at the perches. Today I added the 4 plus another 2 degrees, total of 6. So far, no shake at general driving and ease out. Will shake about 50% of the time at hard take off from stop. Eye balling the pinion angle today it did appear that it was a bit positive. I need to do some more driving to verify all that. Hate to jump to a conclusion. I've done that too often too quickly trying to nail the issue down.
BTW. I checked the motor movement with the brake set and letting out the clutch to try and get the motor to rise toward the right. It does but not much. I feel the mounts are good. Had someone watch that LH mount while I did that and it didn't make any unusual movement.
Also when I say I eyeballed the pinion and it appeared a bit positive, that lead me to adding the 6 degree of shim.
I still can't help but wonder if I'm only band aiding the condition here and the cure is really at the clutch. Myself and the other half dozen guys that have looked at this just haven't found the culprit.
