Cody 82 ZXT Posted December 29, 2001 Share Posted December 29, 2001 How do I tell if I need to replace my U-Joints? I have a clanking noise coming from the back of the car and I'm begging to think that it's the drive shaft. Almost everytime I let out the clutch I hear a clank. Sometimes it is worse than others and I can sit in traffic and just barley engage the clutch and hear the clunk from the back of the car. You can even feel it sometimes. I replace the rear diff. mount and that helped but, maybe that was only part of the clunk, Sould I look elsewhere? Quote Link to comment Share on other sites More sharing options...
johnc Posted December 29, 2001 Share Posted December 29, 2001 Normally a worn driveshaft is indicated by a vibration at speeds in excess of 50 mph. You'll feel and sometimes hear a rumble below your right shoulder that increases as vehicle speed increases. Replacing the trans and/or diff mount will make the sound go away for a short time, but it eventually comes back as the mount gets damaged by the vibration.

Tim240z Posted December 29, 2001 Share Posted December 29, 2001 Crawl under the car and twist the drive shaft and half shafts back and forward (simulating forward and reverse). That should give and instant indication as to where the problem lies. It may be the bolts coming loose, or play in crownwheel and pinion or worn U-joints.

Guest Anonymous Posted December 29, 2001 Share Posted December 29, 2001 Mine makes some clanking noises like this, I believe that it is my rear gears being worn, as the drive shaft has a little bit of play in neutal, not alot, but a few degrees. It kind of makes the clunking noise when I twist it. also, when pulling out my driveway, it often makes wierd noises after I backed up the hill and as I let in the clutch. Maybe this could be your problem too, Just a thought, Kris Quote Link to comment Share on other sites More sharing options...
Cody 82 ZXT Posted December 30, 2001 Author Share Posted December 30, 2001 Worn gear set!! That's not what I want to hear. Your description sounds just like mine. If there is a little load on the car then it does it more than if your sitting on a flat road. Does anyone else think it could be the gear set?
