skyknight789990 Posted August 22, 2012 Author Report Share Posted August 22, 2012 Just rear end an axles funny thing I just got my truck into Portland how much you want for it Link to comment
datzenmike Posted August 23, 2012 Report Share Posted August 23, 2012 Rear ends very rarely go bad. Be sure it isn't a U joint, damaged or out of balance tire or driveshaft or a bad axle bearing. Be a shame to go to all that work and find a bad U joint. What's it doing Link to comment
skyknight789990 Posted August 23, 2012 Author Report Share Posted August 23, 2012 I have a post about it had it at a shop the rear end don't sound good listened to it on a lift the post in in drive train an it's topic is drive train noise Link to comment
datzenmike Posted August 23, 2012 Report Share Posted August 23, 2012 got my truck down to a shop an my u joints are good but my rear end may be done for got a bent right axle an me an the guy at the shot thinks the noise is coming from there it didnt sound to good then i listened to it I don't even know how an axle can get bent. If there is excess play and the wheel wobbles the bearing is likely gone. The cheapest easiest thing is to just get a right side axle and swap it. You could do this yourself. Bet you $10 there's nothing wrong with the axle. Link to comment
skyknight789990 Posted August 23, 2012 Author Report Share Posted August 23, 2012 I have it lifted right now an was checking everything for any Play an nothing I put it in forth while it's up an the right Wheel is moving around a lil my buddy's dad thinks a spider gear is going in my rear end but we are not 100%sure I don't really know anyone who knows datsuns real good an I am Kinda stuck in Portland till I fix it don't want to drive back to Vancouver Link to comment
datzenmike Posted August 23, 2012 Report Share Posted August 23, 2012 Is it still clicking? Can you tell if it's clicking on one side or the middle? Bearings generally growl or groan. Clicking is worrisome. Link to comment

skyknight789990 Posted August 23, 2012 Author Report Share Posted August 23, 2012 Sorry Kinda hard to explain the noise on a forum I have a hard time wording things. I dropped my driveline an my u joints are smooth moving an not sticking or binding took it to a drive line shop an we spent over a hour trying to find out what's going on he said my u joints are good but something is not sounding right in my rear end he had me listen to an it don't sound good it's making the noise as if my carier bearing surrounding is gone but it's fine the bearing is only 5 months old Link to comment
datzenmike Posted August 23, 2012 Report Share Posted August 23, 2012 http://community.ratsun.net/topic/2329-u-joint-replacement/ Ping sound, like a tiny hammer tap on the hollow drive shaft is classic U joint. This is a dry needle bearing jamming and popping loose. This will eventually start a steady squeal. U joints are cheaper and even easier to change. Make sure it's not a U joint. Link to comment
skyknight789990 Posted August 23, 2012 Author Report Share Posted August 23, 2012 I'll get some more u joints an see if that helps but it Kinda sounds like the little hammer thing Link to comment

Well that sucks !! u-joints going out would have been a nice problem to have. have you pulled the cover on the diff and inspect the ring gear/pinion ? Check back-lash ? If it is the a BIG problem with the rear-end ... you are smart to get a good used spare one.... that's what I would do as well ... but it's worth a shot diagnosing it first if you can spare the time and save money :). ( in a sense haha ) $150 for one is really not a bad price these days. $100 would be nice though. As far as testing u-joints ,,, I have taken HUGE industrial pliers and such ,,, as well as special homemade tools just for specific drivelines to test this ( fleet maintenance ) putting transmission in gear ,,, put it up on jackstands ,,,, and trying to twist my drivelines with the pliers to check for ANY slop/movement in them I couldn't see/find any slop a specific driveline ,,, or see any new rust formation around the edge of the u-joint cups ( another sign ) yet when I pounded theu-joints out ,,, one u-joint had 1 cup that was completely dry/crumbled ,,, pressed in new ones on my vise ,,, greased the suckers with the grease gun and walla ,,, solved my issues Link to comment
skyknight789990 Posted August 23, 2012 Author Report Share Posted August 23, 2012 I have one u joint I got a few days ago down trying to get the other 2 an see what that dose when I have the drive line out I'll pull the cover an see what's going on Link to comment
I'm BLUE Posted August 23, 2012 Report Share Posted August 23, 2012 sounds good ! what does the back-lash of the differential feel like ? Driveline bolts are tight ? ( 240z's ... over smaller periods of time or abuse ,,, quite a few bolts in drivelines/halfshafts/etc come loose ,,, as mine did haha ) Did you have vibrations through the floor-boards while driving ?

skyknight789990 Posted August 23, 2012 Author Report Share Posted August 23, 2012 No vibration witch I Should have there is a good bow in my drive line Link to comment
