there is a code on the door jamb sticker then look in your owners manual or crawl under the rearend and look at the tag on the diff cover bolts

>> then look in your owners manual

Truck came with no manual. Any link to a list of the #s and their meaning?
I found the spring info, paint code, etc on the door pillar. But which #s are fr the rear end? WB 142, BRK 4, AXL TR ? Thanks! - Bill
