Dodge Ram pinion bearing adjustment

Asked by: 26 views Transmission question

Hi, I have a 2006 Dodge Ram 1500 SLT Quad cab with a 5.7l Hemi and a 9.25″ rear end. I recently replaced the pinion seal. Before I removed the pinion nut marked its orientation. When I did remove the nut I noticed it was’t too tight and hardly required the breaker bar. I put it back together and returned the nut to its original location. I then drove the truck 100 miles with no trouble and parked it. I have since purchase a SRM and learned about preloading the bearing by torquing the pinion nut to 210 ft lbs. There is no way I did that. I plan on going back under this weekend and using the torque require to turn the flange method of setting the torque at the nut. Did that 100 miles damage the rear end or the crush spacer? Do I really need a new nut per the manual? Why was the nut so loose to begin with? Where did I go wrong? Thanks

    It all depends on how hard you tightened it. If it was tight It will probably not do any damage after 100 miles.

    If your model is a manufactured 2005, maybe this recall could occur your vehicle, and that’s the reason the nut was loose?

    Thanks for the response. When I picked up the new pinion nut on Friday the dealer checked and my truck was not covered by the recall. The pinion nut was only torqued to 37 ft lbs, a far cry from the spec of 210 ft lbs. I replaced the pinion nut and followed the manufacturer’s spec of 210 on the nut and about 20 in lbs on the rotation torque. Both are a heck of a lot tighter than they were. Got my fingers crossed.
