Default Re: rear axle nut torque

Let me tell you a little story about the pre 48 axle nuts.

When I was 18 (1963), my best friend had a 32, chopped and channeled, 5 window coupe, with a 326 CI Olds and a 4-71 blower on top of it. It had a 37 LaSalle trans and a 4500# Hays clutch connected to the rear axle.

We were street racers and after George got the blower, almost every race, we would shear a key. After the 3rd key, we put a 4 ft, pipe wrench on that nut. I can't tell you how much torque, a 150 lb kid put on the nut (150x4ft = 600 ft #, I'd say at least 350 ft#) but, the nut and threads did not strip. At the very next race, the key stayed but, we broke the axle!!!

This picture is after that. We put a Olds rear end and 4 speed hydro behind it.
