ADJUSTMENT - CENTER BEARING
Launch shudder is a vibration that occurs at first acceleration from a stop.
Shudder vibration usually peaks at the engines highest torque output.
Shudder is a symptom associated with vehicles using a two-piece propeller shaft. To decrease shudder, lower the center bearing in 1/8 inch increments.
Use shim stock or fabricated plates. Plate stock must be used to maintain compression of the rubber insulator around the bearing.
Do not use washers. Replace the original bolts with the appropriate increased length bolts.
