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 3.0 mm (0.125 in.) increments. Use shim stock or fabricated plates. Do not use washers. Replace the original bolts with the appropriate increased length bolts.
