Recently I noticed a thumping noise from the right passenger area that is present with the car is at idle (it is not loud enough to be heard if the car is moving) and when the ignition is on but the engine is off. Any thoughts?

    Wasn't sure where to post this but we just last week a 2004 Yukon. Love it! But, when you turn it sounds like there is a pop coming from the steering column. It does so more when you turn right than left. Anyone have this problem? I kind of noticed it when we test drove it but decided against getting it looked at because for one it is still under manufacturer's warranty and we got an extended warranty that virtually covers everything so we took our chances.

    Thanks!
  • I just had the exact same experience with my recently purchased 2004 Yukon XL. It seemed like a tennis ball rolling around when you turned. My mechanic said it's a common issue with these SUV's and GM has a steering unit lube kit for $19.95 that took care of the noise. No problems since then.
  • I Have a problem with some sort of engine noise which my friend said sounded like the Injectors, so I had them cleaned today! Wasn't the problem. Could it still be somthing to do with them? It sounds as if a helicopter has landed in my engine, NO kidding. Doesn't do it when it's first started but after about 30 mins and it's nice and hot you hear it loud and clear! My service advisor said it was "normal" RIGHT! It also gets louder with when raising RPMs in parked position.
    My husband is deployed to Iraq and I'm burnt out of getting no where! I had a belt replaced about 4 weeks ago. Before this happened.
    I'm trying my best to do this on my own, I have no choice, I don't like the dealership here locally but next one is 1 hr away. My service advisor back in TN always made sure any problem I had got fixed, and didn't push me aside. But stationed here in KS now....Someone also suggested cracked exhaust manifold? I just need some help here, also it seems to be when parked it idles rough/shaky since having the injectors cleaned??????
  • HEY THERE, I TOO HAVE THE SAME PROBLEM WITH MY 2002 DENALI AND TOOK IT INTO THE DEALER ABOUT 4 TIMES AND ALWAYS WAS UNABLE TO GET AN ANSWER. RECENTLY AT THE GMC DEALERSHIP, I WAS TOLD THAT THE NOISE (GRINDING AND POPING) WAS COMING FROM THE STEERING SHAFT. GM HAS A BULLETIN ABOUT THIS PROBLEM AND ARE SUPPOSED TO BE GETTING THE UPDATED/CORRECT SHAFT TO FIX THIS PROBLEM. IF YOU HAVE EXTENDED WARRANTY YOU'RE GOOD, IF NOT IT IS GOING TO BE AN OUT OF POCKET EXPENSE. HOPE THIS HELPS

    I recommend turning off your CAPS LOCK. People tend to ignore message typed in ALL CAPS.

  • I don't know about a helicopter noise, but if it sounds like a prop airplane trying to take off when you raise the rpm of your vehicle when the temp is nice and hot than, believe it or not, this is normal. Your motor has a cooling fan that is attached to a fan clutch that is thermistaticly controlled. When your motor/radiator get to a certain temp then it will engage and cause your fan to turn close to the same rpm as the motor. When it cools down the clutch disengages and the fan turns at a fraction of the speed of the motor. If you want to test if this is the noise, than let your engine get nice and warm to were you hear that noise than bring your rpm up to about 2500 rpm (in park) and hold it. depending on the outside temp the noise should go away as the radiator gets cooled off and the fan clutch releases. A way to speed up the process is to "mist" some water in front of the radiator and it will do a swamp cooler affect and cause the fan to disengage faster.

    As far as your rough idle after your injector flush, I would run a tank of good quality gas though it and than see how it runs. They may have put in a tank additive. if you still have a rough idle, than take it back.

    Hope this helps, and that your husband makes it back soon!

    gmclover, hopefully by now your 04 Yukon is all fixed and running normally... If so, can you share what were the problems and the fixes?

    Anyhow, it is possible that during the process of removing and installing a fuel injector, so dirt may gotten in to the fuel rail or one of the injectors and caused the rough idle... assuming each injector was properly cleaned. Just a side note, if I'd to clean the fuel injectors I would also replace the fuel filter too(unless the filter in built in with the fuel pump inside the fuel tank, then forget about it).

    I had a (small) cracked exhaust manifold once, I am not sure if I would describe the noise as a landed helicopter (sounded a bit flat, in my case it sounded more matel-ish, higher pitch); anyway, there was certainly loud Ticking sound when the engine was hot, shifter in Park or at low RPM with no load to the engine... Are you able to tell if the noise is coming from which area of the engine (e.g. top center close to the Intake Manifold, Right/Left front/rear close the valve cover, or front center close to the fan belts, and etc...)?
  • A guy at the dealership who listened himself told me that its not a normal noise, but it seems to do it when it gets hot and obvioiusly pressure may be involved, the longer the engine is on and geting hotter, the more pressure its building...but he wasn't the service guy, just a guy who has a suburban..He told me where to take it, I just have a lot on my plate right now and I'm trying to get there..lol I will keep ya'all posted! Thanks for the replies

    Have you found your problem yet? I have an 04 GMC and just recently had to change the belts and when we changed the belts the tension pulley started making this tapping noise big time and I am on my second tensioner pulley and for some rreason this makes a loud clicking noise mine is the one locatyed at the bottom and runs the smog pump and I was wondering if you figured your problem out yet.

    Have a fan belt tensioner on a GMC 04 and when replaced it started to chatter, it eliminated the bearing sqeel but now I have a loud chatter noise and it stops when the rpms are increased. any ideas out there!

    I need to take it in still, just not ready to have another person tell me, well if your check engine lights not on..don't worry? (grr)I have somewhere I am going to take it, I was actually given the name of another mechanic, here where I live...My yukon still smells like new...but has this issue? go figure! My noise seems to be (on the left hand side when looking under the hood) somewhere middle to the bottom, just hard to tell. I will repost when I get it figured out (hopefully). :confuse:
  • I just took delivery of a new 07 Yukon Denali. It has the navigation system and every time I open the door, I hear a faint sound like an autofocus camera focusing. The only thing I can think it is would be the navigation system rreading the disc, but the vehicle isn't running. Has anyone else noticed this?

    Anytime you open a door on the vehicle when it's been sitting for some time, the NAV unit spins up and gets ready to do it's thing. It will also run for a while after shutdown.
  • I have developed a "Popping" noise that comes from the front of my XL Denali when making sharp right and left turns. The dealership recommended changing the fluids (which we did) and the sound still persist. I had already put new CV shafts on both sides which also did nothing to cure the problem. The service tech said it may be a "Carrier Bearing" in the front differential. Has anyone else come upon this problem? If so what was the fix.

    Does this happen both forward and reverse? slow speeds? If so, it could be a loose cross member. Is it felt in the steering? Could be in need of a replacement intermediate steering shaft. More details would help.

    I brought home my '08 Denali and the engine/exhaust noise is a loud rumble any time I turn on the car or touch the gas. The dealer said it is normal for the Denali engine but I don't remember this when I test drove. Any ideas or anyone with the same problem?
  • I hear the same noise in my '07 Denali. I just completed my 5,000 mile service, and asked the dealer to check out the whirring sound (which, at times, is not so faint). They said that it was a normal radio or cd/dvd start up sound. I am not convinced of that, but had to get back to work, and didn't have time to argue. I will go back to the dealer when I am in the area, as it is annoying.
  • Hello. I am hearing an annoying rattle right above driver's head anytime I hit a bump in my 03 Denali. I think something is loose where the speaker looking grate is in the headliner. If I apply pressure to the grate, it seems to go away. The dealer said they would have to take apart the entire headliner to tell what it was, and this would risk causing even more annoying rattles. Any ideas of an easier fix? I'm tempted to pry the grate off and see if I can put padding in through there, but I don't want to cause more damage. Any thoughts? Anyone else had this same problem?
  • I am having the same rattling issues in my '05 Denali. Let me know if you figure anything out tpwallac. Thanks.
  • I have a 04 XL Denali. Recently when I am turning, I hear a sound, not sure if it is a grinding sound or what it is. But when I straighten the wheel, that sound goes away but I can tell there something that is not right. The sound comes and goes. Anyone have any insight to this?
