Fellas, I'm pretty sure this thing is almost kaput. The rattling has gotten louder than the actual motor and is really making me nervous. Does anyone know of a good aftermarket replacement? GMC Dealer wants $300 for it. Does anyone have any experience in replacing it? Is it a royal pain to get out? Does anyone have a schematic or drawing or maybe a dealer instruction on how to replace? Please help. We are going back and forth to Fall River every day for the next few weeks and can't afford to be down a truck for more than a day. HELP! BTW the truck is a 2003 Chevy 3500 LS LB7 auto CREW CAB 4X4 dually w/utility bed. 160k mi. no aftermarket parts yet. Please help. Thanks in advance. Your help is very much appreciated.
