Service bulletin 030400

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

AN INTERMITTENT BUMP (STOP-BUMP) ONCE THE VEHICLE IS BROUGHT TO A FULL STOP. THIS CONDITION MAY OCCUR 3 TO 20 SECONDS FOLLOWING THE STOP OR WHEN THE LOAD ON THE REAR DRIVELINE IS REDUCED (E.G., WHEN THE APPLIED BRAKE PRESSURE IS DECREASED). THE STOP-BUMP CONDITION MAY BE THE RESULT OF A BINDING BETWEEN THE SPLINED SURFACES OF THE REAR PROPELLER SHAFT SLIP YOKE AND THE REAR OUTPUT SHAFT OF EITHER THE TRANSFER CASE OR THE TRANSMISSION. *TT
