THIS BULLETIN CANCELS AND SUPERSEDES DEALER SERVICE BULLETIN 88-215-4C, DATED MAY 1988. REVISED PROCEDURES FOR AXLE BOOT CLAMP INSTALLATION ARE PROVIDED IN THIS BULLETIN. ALL COPIES OF 88-215-4C SHOULD BE DISCARDED.

Starting with the VIN numbers listed below, the 1988 K3 Inboard and Outboard Front Axle Boot Clamps were changed in production from a crimped to a swaged clamp design.

PLANT VIN

Pontiac East 1 GBGK34K9JE183526 Oshawa 2GCGK39N5J1255838

The same change took place for the K1 and K2 models with the start of the 1989 model production.

The old style crimped clamp required a stamped metal protector pressed onto the outer C/V joint housing around the clamp.

The new design swage clamp has a smooth finish when installed and does not require a clamp protector.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
