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 1GBGK34K9JE183526
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.
