Re: Servicing a Model 20 Rear axle question?
Pinion Seal is like any other Pinion seal. some say you should replace the Crush sleeve everytime to pull the pinion nut, but I know of those who have measured how much torque it took to break the pinion nut loose and retightened it to the same specs.. and been fine.
axle bearings and seals... yes the axle bearings are pressed on. you can pull the hub to get to the outer seals, but I'd advise against that. I'd pull the whole shaft, cut/bust the old bearings off (After checking to see if they even need to be replaced) and pull everytthing off the diff end of the shaft. you start messing with the splined hub, and you're liable to only start more problems.
Actually, if it was me, I'd toss some One piece axles in tehre for $200.. comes with bearings and inner and outer shaft seals not to mention one piece shafts. you mihgt check with Ricky on this board. He's an Omix dealer (check the For sale thread) and they have some one piece axles. that's what in my AMC20 and they're holding up great.
