SUBJECT:
SEAT MOVES FORWARD DURING BRAKING WHILE UNOCCUPIED (INSTALL BELLEVILLE WASHER)
MODELS:
1991-1992 C/K WITH HIGH BACK BUCKET OR 60/40 SEAT (RPO AE7, A50)
Owners of some 1991-92 C/K vehicles may comment that the passenger seat back moves forward during moderate braking if no one is in the passenger
seat. The motion of the seat back may cause the easy entry feature to operate, allowing the entire seat to slide forward. If the seat is occupied, the seat
back will not move.
To correct this condition, a new positive stop bolt (P/N 15633613) and Belleville washer (P/N 15665757) should be installed on both sides of the
passenger seat. The Belleville washer has a special conical shape and MUST be installed with the point side of the cone pointing toward the bolt head.
The conical washer is needed to increase friction during forward seat motion.
SERVICE PROCEDURE:
1.
Raise the seat cover and the padding to expose the seat back hinge.
2.
Remove the seat hinge positive stop bolt and discard.
