Hi all, really looking for some clarification here. I have a 1997 Dodge Ram 1500 4x4 360 w/ a 9.25 rear end. Had ABS probs, so opened the rear diff to inspect the tone or exciter ring for bad teeth, I found two teeth bent up and the reason was my diff is trac loc and the clutch holders had broken up and found them lying on the magnet.
Because of this I pulled the whole setup, axles, pinion, and diff to replace all the bearing and install new clutch pac on the trac loc.
So now I’m stuck because of various docs stating different torqe specs.
Here’s my dilemma.
Looking at the Dodge 94/95/96 FSM all state that the pinion pre-load is 20-30 inch pounds, and lists the torque for the new ring bolts at 75ft lbs. The 98/2001 FSM’s all state pinion pre-load should be 15-35 inch pounds and 115 ft lbs torque for the ring bolts.
I’ve currently got the pinion preload set at 30 inch lbs.
I’m wondering which is correct and why they changed. I don’t have a 97 FSM, just the ones listed above that I pulled info from. Should I simply go w/ the later FSM's torque? Did they figure something out that wasn't noticed in 94-96? I believe I'll be fine w/ 30 inch pounds, but not sure, It’s not a big deal to pull the yoke and install a new crush washer to reset pinion preload to a bit less.
Thanks for any advice!
