    ok hi its me again. when i waz at 7 11 i put in reverse and i herd a prity bad clunk and i put in drive just to see if would do it .it did. so i went home and i put 80-90 in the tranzfercase and that dident help and i replaced all of the u joints. i think it is the rear because i put it in nutral and i went under neath and moved the drive shaft and there is play in it . is this gonna mess up my gears or cause me any problums.?? its a 10 bolt

    OK then it might be in the pinon bearings have you ever took one of these rear ends apart .you are going to have toget in there be sure to watch for shims on each side of the ringgear or maby get another rear with the same gear as the front

    Could be bad motor mounts too......


    I've got a clunk like that going into reverse, but I've been too lazy to replace the mounts.

    Mine is either noew or rebuilt everything from the tranny back , and I still get a clunk once in awhile . Torque gets transmitted from tranny , to case , to rearend , each piece takes up a little slack , hence the clunk sometimes when everything is known good . Add a locker in the rear that works on torque , and adds even more .
