Bearing preload

On a 1980 CJ M20 rear.....whats the bearing preload for the pinion with NEW bearings???? Putting a Detriot in her and figured I would replace the pinion bearings while im at it......the oil was perty nasty! Thanks in advance guys!------------DuNgA!!!!

I shoot for 25-40 in/lb with new bearings. Make sure you dont go too far with that crush sleeve or you'll have to start over with a new sleeve.
