Gavin Posted December 19, 2006 Share Posted December 19, 2006 I have been trying to sort out a problem with my drivetrain for quite some time now. Basically there is play somewhere, which I can feel when shifting gears, jabbing the throttle, etc. I have tried a rebuilding the half-shaft U-joints, replacing the mustach bar bushings with urathane, and have added a sold diff mount (which I know is kinda bad but dont want to hear about it right now). The driveshaft joints dont have any play that I can create using my hands. What else could be causing this? Could it be the diff itself? Thanks a lot, Gavin Quote Link to comment Share on other sites More sharing options...

Gavin Posted December 19, 2006 Author Share Posted December 19, 2006 I had ruled those out since the impact seems to be coming from the rear, but I guess thats where the driving wheels are so perhaps it doesnt mean anything..? Quote Link to comment Share on other sites More sharing options...
JMortensen Posted December 19, 2006 Share Posted December 19, 2006 Worn control arm bushings, worn mustache bar bushings, oose driveshaft bolts, worn stub axle splines... the list is long for possible causes. I think backlash in the diff is probably one of the most common diagnoses and is also the most likely to be wrong. I would be very surprised if anyone ever took a diff out that wasn't howling like crazy and measured and found the backlash to be way out of spec.

Gavin Posted December 19, 2006 Author Share Posted December 19, 2006 I just took a look at my tranny mount and its definitely questionalbe. I can wiggle it back and forth a bit by hand. I'm going to pull it off this morning and give it the Urathane treatment. I have a pair of stubs maybe I'll try those next.. Hope it doesnt come down to that, Im sick of this problem. Thanks guys Quote Link to comment Share on other sites More sharing options...
Gavin Posted December 19, 2006 Author Share Posted December 19, 2006 It was loose because the center nut was loose . Feels better, but didnt fix the problem though, I really think its in the rear... Oh well I'll keep chipping away at the possibilities. Thanks for the direction guys. Quote Link to comment Share on other sites More sharing options...
