GMC NUMBER: 91-10A2-166

GROUP: 10A2 Seats

DATE: December, 1991


CORPORATE NUMBER: 061604R


SUBJECT: SEAT FILLER PANEL SLAP (INSTALL REVISED TORQUE ROD)

MODELS: 1983 -1991 S/T UTILITY VEHICLES


Some 1983 - 1991 S/T utility vehicles may experience a rear seat filler panel slap against the seat back during acceleration.

This condition results from insufficient torque rod spring pressure and may be more evident on the four-door utility vehicle because of the increased height of the filler panel.

To repair this condition, it is necessary to replace the torque rod spring with a larger diameter torque rod spring (P/N 15674883). This condition was initially resolved in production by installing two small diameter torque rod springs. The final resolution was to install a single torque rod spring with increased diameter. Either of the production resolutions will provide increased pressure and prevent the filler panel from slapping.

This condition was resolved in production after the following VIN breakpoints:

MORAINE GMC M2534705
Chevrolet M2224077
PONTIAC GMC Start of Production 1992
WEST Chevrolet Start of Production 1992

Assemble

If two torque rod springs are already installed, replacement with a new larger diameter spring is not required.
