on an 01 1500 what is the pinion bearing preload for new and used bearings?

Call: Ring and Pinion Service Discuss your gears and their settings with them. This can lead to so much back and forth. You can get your answers in a 3 minute phone call. They were nice to me. There were so many "if/thens" Like if the seal is new, and if the bearings are new, and a new sleeve, and a new nut. Then , how does it "feel", that's too tight. back off some. etc.

Dial torqometer, adapters, socket. Dial indicator with mag base. Torque wrench If you have the tools, get the book at the library. They "feel right" when they feel right and too tight is hard to turn rather then slight drag, or some drag. a dead stop is right out. a pattern check can take 2 people to simulate load and Recheck.
