MJ86YJ90 Posted January 10, 2011 Posted January 10, 2011 2 days ago i was backing up my driveway i stopped at the bottom to answer a call talked 30 seconds then let the clutch out and began to go backwards when I heard a clunk. now when i move the truck it sounds like a rubbing coming from the front passenger wheel i took the wheels off and nothing rubbing. the tranny goes in all gears fine so I am not sure its a tranny problem. any ideas?
mkbruin Posted January 10, 2011 Posted January 10, 2011 u-joint? Inner or outer axle shaft snapped? Vaccume disco?
MJ86YJ90 Posted January 10, 2011 Author Posted January 10, 2011 ok so here's an update i took wheels off front calipers everything and found nothing so i went to the back......... i raised it up took it outta gear, and I'm not sure if this is normal but when i spin the wheels the drive shaft doesnt move until i spin the wheel a little faster and it stops moving before the wheel stops and both sides spin at different speeds....... could my rear end be blown???
MJ86YJ90 Posted January 10, 2011 Author Posted January 10, 2011 ok so when the trucks in neutral i spin the back wheels and the driveshaft either barely turns or doesnt at all
88elimnator Posted January 10, 2011 Posted January 10, 2011 Its suppose to do that, unless theres a spool or the spider gears have been welded together.
MJ86YJ90 Posted January 10, 2011 Author Posted January 10, 2011 ok so i just took the truck for a little ride it does it in reverse but not if i drift backwards in neutral. sounds like its only doin it in gear. I am afraid i may need a tranny which is ok since now i can upgrade to a 5 speed.
cody4359 Posted January 10, 2011 Posted January 10, 2011 how bad is the rubbing sound? increase with speed, intermitted,? have you drained your tranny to see if theres metal shavings inside? noise coming from front or rear?
MJ86YJ90 Posted January 10, 2011 Author Posted January 10, 2011 sounds coming from the front no i haent drained it yet it does it the whole time its moving but there is no tranny slipage like an auto ould do when it starts to go I'm thinking maybe the bang i heard was the tranny lol
cody4359 Posted January 10, 2011 Posted January 10, 2011 could be a different noise all together but in my zj theres a rubbing/grinding noise occasionally. its the wheel hub bearing, sealed unit so i can't grease it, but its dryer than dog poop. bearings need lube or theyll be noisey and fail, and the clunk is a sign of bad u join/cv joint. drive it til it breaks, then ull know for sure what it was :yes:
MJ86YJ90 Posted January 10, 2011 Author Posted January 10, 2011 It def sounds like something up front but it only makes the noise while in gear if i let it in neutral and drift its fine soon as i am in gear makes rubbing noise....... :fs1: money pit
cody4359 Posted January 10, 2011 Posted January 10, 2011 maybe try taking the front driveshaft out and thatll tell you if its your front u joints or not..... but then again not like your engaged in 4wd when ur cruising. worth a try since its free
cody4359 Posted January 10, 2011 Posted January 10, 2011 hmm dunno what to tell ya then :dunno: if its coming from the front and its a 2wd wheel bearings would be my guess, but it only does it when its engaged in gear.. throwout bearing or piolot bearing???? thatd should be a fairly cheap and easy fix. kinda hard to tell without tearing into it. rarely but sumtimes you can talk to a tech at the dealership and theyll partly help diaganose it
Curt Posted January 11, 2011 Posted January 11, 2011 Check the tranny mount/exhaust hanger. Mine was rubbing there in a spot I couldn't easily see. I fixed it with shims under the tranny mount bolts.
