Torque Specifications
For all the times you have been working on you jeep, or what we call our jeeps, and realize that your FSM doesnt have the torque specs for that ford 9 or Dana 60 you swapped. Instead of going out to buy a FSM just for a rear axle. I have done some research and have put together this nifty list of torque specifications for common axles that we swap into our rigs.
Dana 44
Ring Gear Diameter=8.500"
Pinion shaft Diameter=1.376"
Ring Gear Bolt Count=10

Front wheel bearing torque procedure
Step 1: Torque to 50 LB while spinning hub
Step 2: Back off, then torque to 35 LB for automatic, or 50 LB for manual hubs
Step 3: Back off 3/8s of a turn for automatic hubs, or just enough to free the bearings (1 LB) for manual hubs
Step 4: torque front wheel-bearing outer lock nut to 160 LB

If anyone finds these numbers dont work or differs from you FSM please let me know. I got these numbers from two FSMs I have and the Internet. Im sure over the years and with all the different models of axles the torque numbers may change. This is only a guide.
I hope this helps.
