I had a leak on the rear end so went looking for the problem, it seems the retianed on the drivers side to hold the axle in was loose . So I pulled the axle and fixed the problem . But then i went to check end play and does not matter what i do cannot get the correct end play . The rear end is a sure grip and has the bearings tat you have to grease . I have rear can chagne up to sealed bearing , looking for suggestions . When I did have the axle out icould see the end of the other axle ... Help
