Axle Bearing preload setting

I replaced axle bearings on a 1972 4x4, all factory setup. I am looking for instructions on setting the preload. I found this on another website. Does it look right?


Tighten adjusting nut to 50 ft-lbs/68 Nm while turning hub. Back off and retighten to 35 ft-lbs/47 Nm. Back off 1/4 max. Holes in washer must align with tang in slot in spindle. Tighten locknut to 50 ft-lbs/68 Nm. Endplay should be .001-.010".

Re: Axle Bearing preload setting

I snug it up while turning (50ft/lbs - I don't use a torque wrench). Then back it off & tighten as tight as I can by hand (no ratchet on socket) then lock it down. If the lock washer holes don't line up I back it off till they do.

If you do it as you stated (the correct way) then check how tight the nut is, it will be hand tight. (subjective - some people have large hands!)

Re: Axle Bearing preload setting

You must be working on the front axle? The instructions I have always followed are the same as step one and step two that you have, this is to insure the bearings are fully seated. After tightening to 35 ft/lbs, I back if off again, then turn the adjustment nut until it makes contact, and turn it 1/4 turn. That sets the preload.
