I am so tired of being told that my 2003 Z71 loud "clunk" is normal that i'm about to go to a ford. This is a pile of sh * t....When i bought it, there was no "clunk", so why now??? I will tell you why...........Fraud. Gm knows they have a problem, but will not fix it because it will cost a little of their money, but what they do not realize is they are losing customers everyday. This is all over the internet and people are chosing other brands of trucks everyday. Please e-mail me if you have had this problem and had this "Clunk" fixed. If you had it fixed you are one in a millon!!!

Thanks, Gene

Tinie, where's the clunk coming from? What do you do to make th "clunking" sound?

I'm assuming it's in the front-end of the truck, and part of the steering.

BTW - We had a 2001 Ford F250 Super Duty and it clunked too! The problem with the Ford was poor body mount design. So you may want to re-evaluate if changing vehicles is the right thing to do.

I did actually get my 'clunk' fixed. It was the intermediate steering shaft that was causing the noise, when I would round corners or hit bumps it sounded like something was loose in the front end, like a bushing. My local dealership ordered this part for me (under warranty) unfortunately it took nearly 3 months to get the part in from GM as they are on backorder. Once it was installed though, it made a world of difference in the way my truck drives and handles. Get your name on the list, it is worth the wait!

I'm assuming that this topic is about the popping noise in the steering shaft. I have read most of the older post in the archives about this exact problem, and one poster mention that he had his fixed after ordering a $30 kit from the dealer ship. Hey catski how much did it actually take you or should I say cost you to fix your problem?

I also think tinie has a point about what GM puts out, but again you could say that about any other brand of vehicle as well. These little problems that we come across is a pain in the @ss with the popping noise in the steering shaft, the fuel gauge malfuction, the window motor problems and the list could go on and on. But this is life of any car or truck owner in america not depending on brand of any kind. Lets just get it fixed and go on to the next problem we come across.

I was reading an interesting article the other day (don't ask, I can't remember where it was) about an interview that was being done at some folks with Raytheon (they make a lot of our military's missile systems). Anyhow, the jist of the article asked what was considered as an acceptable rate of failure. The guy mentioned that something along the lines of 15% failure rate was considered acceptable (that is, missiles didn't launch 15% of the time).

Apparently, based upon that "acceptable failure rate", the government was pushing Raytheon to work closely with companies like GM, Toyota and Ford. Reason: Although we live with small problems (fuel gauge malfunctions, window motor problems, etc.) with our vehicles, the failure rate on a complex piece of machinery such as a 4-wheel drive truck is less than 1 tenth of 1% (I think that was the number). Essentially, the gov't was requesting / suggesting to Raytheon (and others) that they figure out how to make things work better than 85% of the time and get a serious lesson from the QA departments at companies like automobile manufacturers.

If you really think about it, in the last 15 years, when was the last time your car/truck didn't start due to some mechanical failure (take human error OUT of the equation). You probably start and drive your car 700 - 800 times per year and you might have one failure, maybe, where something major doesn't work.

Obviously there are exceptions to this rule, but the vast number of cars and trucks on the road start, go and shut off when you ask them to.

The flip side to this is, and this is my humble opinion, I'm paying a dope-load of money for a new 4-wheel drive truck ($30-$40K!) and I'd better get my money's worth! :)

This is a loud "clunk" from rear end or drive train that is getting worse with time. It started around 14,000 miles and has not quit since. When you start off from a dead start you will here this "clunk". GM tells me this is normal. This is not the steering "clunk" i had that fixed already after they greased, greased, then i told them to replace the intermediate shaft and that fixed it. Please keep any info coming.

Thanks, Tinie

Hey Tinie.

Try grabbing the rear drive shaft and rotating it back and forth and pulling/pushing on it. You may have worn out u-joints.

If that doesn't do anything try this: Put the truck up on jacks and support it on the axle. Try turning one tire forward and backward in jerky motions. See if you can reproduce the noise there. (You may have problems with the differential or ring/pinion gear).

Also, check for loose lug nuts. Sounds simple, but something to look at.

Lastly, try pulling and pushing the tire in and out (towards and away from the axle). See if there is any play as this might indicate a worn or broken CClip / differential problem.

Let me know if either of those reproduce the noise, or not. We'll continue to troubleshoot after that.

tinie...

I have a 2001 Z71 with 59,000 miles, and I get the same clunck noise when I first put the truck into drive, but have not been able to figure out what it was. Sorry, misery loves company!

Is the clunk you get in your truck a hollow, metal, "tinny" type sound?

I know that it is comming from the rear end. It almost seems like the U-joints need to be replaced, but there is no play in the driveline. But it does sound hollow, metal, and tinny.

My buddies '98 did the same thing. He saw several mechanics and they all said that it was normal. He also put over 85,000 miles on it and never had a problem. I *think* that it was just the driveshaft echoing the tranny going into gear. If memory serves me correctly, the driveshaft was a monster, about 4" in diameter or larger. My guess is that it's just reverbarating and making some noise.
