    Need some help? Rebuilding my 8-1/4 rear end with sure grip . My Hayens manual does not show torque spec for the differential cross pin bolt? and do I use red loctite or blue on the threads?and is the torque in inches or lbs? I think inches cant be very much?

    I did some searching - can't find a spec for that either - the torque spec can be either in.-lbs or ft.-lbs - depends on which item you are torqueing -- 12in-lbs = 1 ft-lb.
