I replaced the shocks all round and have the longer units in the rear to accommodate the super stock springs.
Did you check/reset the pinion angle when you put those springs in?
The fact that you said it went away , for the most part , with snubber bars up against the rear springs tells me it's a driveline issue. Pinion angle is the first thing to look at.
Where's Quicktree ?
Yes I did experiment with the angle shims after putting the new springs in. I've looked at this pinion angle allot and tried different negative angles with no success in getting rid of the shake.
Another odd thing to me is that when I set the mercy brake and bump engage the clutch, I get no shake. That test led me to the rear thinking the motor, tranny clutch area was fine.
How about an actual pinion angle reading ? Was negative actually the correct way to go ?
Yes. Negative is where you want to be in relation to the tranny tail. My readings have been anywhere from -2.5 to -8, depending on what shims I had in place.
