I'm hoping to save somebody some money someday. I just replaced the kingpins in my 2003 chevy c4500 kodiak topkick truck. I could not find the parts from anywhere except the dealer, so I dropped the $577.00 for the kit.... GM part # 88936084 The parts are in a ArvinMeritor box there was kit # of R201476 for Axle MFS-6 or MFS-06 in the instructions.... It looks like I could have got the same kit online for $218.00... I may even be able to get the tie rod ends for $65.00 for both left and right instead of $250 for one. Everyone needs to make money, but sometimes the dealership seems to need too much. Oh ya, ABS Module ECBM no traction control #19133318 well over $1000 at dealer, $75.00 w/shipping on ebay.
