The Ford Barn - View Single Post - Torque Tube to Differential 6 Bolts

I would tighten them to "Just tight" about 35 / 40 lbs with a 3/8 rachet. This is not super tight. I think it's just about right. Henry Ford used a fine thread and a tighter than usual thread fit on all the nuts and bolts. Don't ever "Chase" the threads with a tap or die. Use a wire brush or a three corner file to remove nicks in the threads. A die will take too much off the thread. Henry was being ultra conservative using safety wire. The only place I have seen this is on airplanes. So, Between the tight bolts, the fine thread, the tighter than usual fit, and the safety wire, do you honestly believe the bolts will come loose on today's relatively smooth roads?
