47-59 torque spec

I've never seen one that backed out because it wasn't tight enough. I have seen a bunch of broken ones because the pin for the spiders got loose in the housing for one reason or another.

One of the worse ones was in the 75 Chevelle my mom bought new in 75 and drove for years. the end of that bolt broke and the pin worked it's way out and caught the case and broke off in chunks. That was by the east bound Selah rest area in the dead of winter in 20 Below weather. The only time she ever called me collect in her life. You get a collect call from your mom in the middle of the night in below 0 weather and you take the call. I got hold of a friend who picked it up with his wrecker and her companion went up and picked her up in his car. The pin had come out far enough that one of the spider gears had fallen out and the car wouldn't move and a state patrol pushed her up into that rest area.
