HELP!! i have a 98 ram2500 4x4 with a nv4500 trans,and a Dana 80 rear diff .i changed my leaking pinion seal 2 weeks ago i have did this on trucks before. i always mark pinion stud and nut,count the threads and return to where they were before. now i have a drive shaft yoke that is wobbling badly, the nut is still tight .I think it is the pinion bearing. Is it possible to remove the pinion gear and bearing.and replace the bearing and crush sleeve and just re-torque. or will everything in the rear end need to be reshimed and adjusted. THANKS STUCK IN GEORGIA!!
