2002 CHEVY HD EXT CAB. I TOOK MY PICKUP TO A GM DEALER BECAUSE I KNEW THERE WAS A RECALL FOR THIS ISSUE. THEY TOLD ME THAT MY PICKUP WAS NOT INCLUDED IN THE RECALL. THE BRAKES SHIFT INTO ABS WHEN COMING TO A STOP ALL THE TIME. IT IS CLEAR THAT THEIR IS AN ISSUE WITH THE ABS BRAKING SYSTEMS IN PICKUPS IN THE NORTHERN REGIONS DUE TO SALT, STATED IN THE RECALL FOR NEWER MODELS. I CALLED GM CUSTOMER SERVICE AND THEY TOLD ME THAT THE 2002 PICKUPS ARE NOT YET INCLUDED IN THE RECALL. THIS IS A SAFETY ISSUE THAT SHOULD BE RESOLVED BY CHEVROLET. PLEASE HELP!! *JB

ROUTINE MAINTENANCE REVEALED A LEAK IN THE TRANSFER CASE. THIS LEAD TO DISCOVER A SMALL HOLE IN THE CASE. THIS IS CAUSED BY A PART DEFECT THAT BREAKS OVER TIME. USUALLY AROUND 85,000 TO 105,000 MILES. THE PART IS AN "ANTI-RATTLE CLIP" THAT PREVENTS THE INNER PUMP FROM OF COURSE RATTLING. WHEN THIS PART BREAKS, THE PUMP THEN RUBS A HOLE FROM THE INSIDE OUT. IF THIS IS NOT CAUGHT IN TIME, THE LUBRICATING OIL WOULD RUN DRY AND THIS WOULD LEAD TO A DRIVETRAIN MALFUNCTION. I WILL BE ORDERING A REPLACEMENT TRANSFER CASE. YES OLD PART WILL BE AVAILABLE. NOTE: AS OF YET, THE REPLACEMENT PART FOR THIS HAS NO MODIFICATIONS TO PREVENT THIS FROM HAPPENING AGAIN. *JB
