Wheels - Crosslace Aluminum Center Cap Missing

Group Ref.: Steering/Suspension

Bulletin No.: 333503

Date: January, 1994

SUBJECT:
WHEEL CAP RETENTION (REPLACE ALL CAPS WITH SERVICE KIT)

MODELS:
1993 PONTIAC BONNEVILLE WITH CROSSLACE ALUMINUM WHEELS (OPTION N60/N73)
VIN BREAKPOINTS: SOP THROUGH P1241675

Condition:
Some owners of vehicles within the above listed VIN breakpoints may have missing wheel caps.





Cause:
On vehicles built with the above breakpoints, the cap retention fingers do not engage completely. There was a running change made to the wheel that allows the retention fingers to grip the wheel properly. Early design wheels can be identified by measuring the wheel center cap area as described in the illustration.

Correction:

1. Check the dimension shown in the illustration. If the measurement is 11.2 mm or greater, replace the wheel caps with service kit, P/N 25623872. The four caps in the service kit have retention fingers 1.5 mm longer.

Removal of the wheels is not necessary to replace all the remaining caps. Drive a sharp punch into the cap and pry out.

Parts are currently available from GMSPO.
