Had wander and driveline vibration, my shackles are approx 1 1/2 inches longer than stock with Rancho 2 1/2 inch lift springs. Just put in some 4* spring shims in the front and back. Wander is gone woohoo. Driveline vibration is gone on the highway (65 mph to 75 mph) which is awesome because I do alot of hiway driving. But now I have a driveline vibration on the regular streets in 4th gear (35 mph to 45 mph) (I say 4th gear because in 3rd the 350 is going pretty good so I can't tell if its the engine or the driveline)
My question is: Do you think I should:
a)Live with it
b)Change to 2.5* spring shims
c)Change to 2 1/2 inch longer shackles
d)Take out the shims?
Thanks
