SUBJECT:
Shudder Pulling Away

NOTE:
THIS BULLETIN APPLIES TO 1500 SERIES 4X2 SHORT BOX CLUB CAB VEHICLES EQUIPPED WITH A TWO-PIECE PROPELLER
SHAFT AND AUTOMATIC TRANSMISSION ONLY AND REVISES TSB 16-01-94 FOR THE VEHICLES SPECIFIED IN THIS NOTE.
SYMPTOM/CONDITION:
The vehicle may exhibit a driveline shudder while pulling away from a stop.
DISCUSSION:
Launch shudder may be due to undesirable driveline angles and may become worse when the vehicle is used at or near its maximum GVW rating.
As the vehicle is loaded, the driveline angle will change. In the case of maximum GVW, the rear differential may rise above the rear propeller shaft
center bearing when the vehicle is launched from a stop. The resulting driveline alignment could cause a shudder in the driveline.
NOTE:
REMOVAL OF THE CROSS MEMBER AND REPLACEMENT OF THE TWO-PIECE DRIVELINE AND CENTER BEARING SUPPORT
BRACKET WITH A SINGLE-PIECE PROPELLER SHAFT WILL ELIMINATE THE DRIVELINE SHUDDER AT ANY VEHICLE LOAD.
