Models
Affected: 1987-90 SUNBIRD AND GRAND AM MODELS


Customers may comment about a "clunk" or other noise from the engine compartment when turning, and may also comment about a slight feeling of looseness in the steering system.

As part of troubleshooting, inspect the steering gear to front of dash clamp retaining nuts. If it is determined that the nuts are loose, replace them with new torque prevailing nuts, P/N 22552523. The nuts should be tightened to 32 N-m (24 lbs.ft.) per Service Manual procedure (tighten LH or drivers side first, then tighten RH side).

These new nuts are being installed in production starting with the following VIN breakpoints:

GRAND AM LANSING LC339330
SUNBIRD LORDSTOWN L7601342

Parts are currently available from GMSPO.
