goodguys75 Posted February 19, 2010 Share Posted February 19, 2010 a while back someone on the forum was a chevy tech, i think it was dunefreak, but not sure. I have a 2003 chevy tahoe 2x2. when i drive over a bump with my rear end i hear a clunk, sounds like it could be drive line u-joints or something in the suspention. If i jump up and down on the rear bumper i can make it clunk. Is this a problem with the tahoes or is it just a random thing??? been driving me crazy for the last 5 mo...any input would be great if any one knows what it is or has had the problem before.. i hope the chevy tech chimes in, maybe he knows what is wrong...thanks :?: Quote Link to comment Share on other sites More sharing options...

sandawg Posted February 20, 2010 Share Posted February 20, 2010 have you checked your shocks? my wife's 2003 hota did the same thing and it was her shocks.... Check the shock mounts for loose rubber bushings or loose mounting bolts. IF the shocks were bad they would show oil on the bottom portion usually. Make sure it is not bottoming out on the rubber stops between the frame and the rear axle. Quote Link to comment Share on other sites More sharing options...
goodguys75 Posted February 20, 2010 Author Share Posted February 20, 2010 i dont think it is the shocks, but i will look a little closer. sounds like when the rear end moves the drive line u joint is making the noise???? Quote Link to comment Share on other sites More sharing options...

If it's a U joint it should cause the vehicle to vibrate, in my humble opinion! A clunk is something that is loose or missing a rubber bushing or something like that! Does it sound like metal to metal or something else? Is it a clink, a clunk or an oh sh*t???? Quote Link to comment Share on other sites More sharing options...
dunefreak Posted February 20, 2010 Share Posted February 20, 2010 Damnit I thought I was done with work for the day. :argue: j/k One very common problem is the driveshaft slipyoke binding and clunking. The splines get dry and stick. Typically it is on take-off from a stop though. You say it makes the noise when you bounce the truck up and down just sitting there? hmm Have somebody lay under the truck and feel and hear where the noise is coming from. It could be a shock or other suspension component. Can you describe the noise in more detail? Does the driveline make a metallic noise when it does it? BTW, I've never seen a 2 wheel drive, 2 wheeled Tahoe. (2x2) jk Quote Link to comment Share on other sites More sharing options...

(2x2) jk I thought it was u...it does happen on take off. and i really dont think it is the suspension, going to get a closer look in the am, but i really think it is somewhere in the rear of the driveline.. the noise is around the rear end area and there is no vibration at all.. does this help at all??? thanks alot for your input Quote Link to comment Share on other sites More sharing options...

dunefreak Posted February 20, 2010 Share Posted February 20, 2010 I thought it was u... Yep, but there are a couple other techs from Hend Chevy on here as well...sand~snake & sanddunesaddict It definitely sounds like the slip yoke is binding. Here's how to fix it... 1) Open & drink beer 2) Remove the driveshaft (4 bolts at rear u-joint) 3) brake clean the driveshft front slip yoke out and wire brush the splines nice and clean 4) On inside of the slip yoke pack the splines with some STEELCO red grease. 5) reinstall shaft sliding it in and out (hu hu lol) to make sure the grease gets worked in nice and good. 6) finish beer before it gets warm Quote Link to comment Share on other sites More sharing options...

dunefreak Posted February 20, 2010 Share Posted February 20, 2010 The recall was for the intermediate shaft. I don't know if it would be covered again, but I can check on it. We stock the hell out of those. That's wierd it took so long to order. I will find out on monday if I can remember to check. Maybe post or pm me your VIN # so I can pull up the claim history to check on it. Quote Link to comment Share on other sites More sharing options...

dunefreak Posted February 24, 2010 Share Posted February 24, 2010 Hey Andre, I checked on the intermediate shaft. The part # that was installed on your truck was an updated part at the time, but they have since revised and improved them a couple times since then. There wouldn't be any warranty or coverage on the one you had put in since it was quite some time ago and the age of the truck. A new one costs about 104 bucks. I think that is list price though. Let me know if you end up needing a new one. I can save you a few bucks. Quote Link to comment Share on other sites More sharing options...
