Replying to: tryn2comeup (Jan 22, 2008 10:47 pm) The two motor devices you might hear are a fuel pump (usually can't hear this, unless it's going bad), and the air pump for the auto leveling suspension (if you are a higher trim level with this option, you can definitely normally hear this pump).

I know its not the fuel pump because i can hear it cut on when i turn the key (when it runs for a few seconds and cuts off)....So im assuming it would be the other is there any way of stopping the sound and what do you mean by if i am a higher trim level?...

#19 of 36 intake? by pagimeno Jan 23, 2008 (12:34 pm)
I have a 97' Tahoe with 130k miles.....and when the engine runs cold or warm runs perfect, but as soon as it's hot, like after 15 mins....it starts the noise, when I accelerate it makes this slapping, valving noise, I changed the Throttle Position Sensor, and it's seems a little better, but not enough.....it's driving me crazy. A mechanic I asked told me might be the Lower Intake, another one told me the Upper Intake....should I change the gaskets only? would be enough? or I should change the manifold too? Any ideas on what can I do? THANKS!
#20 of 36 engine chirping noise by debbu Jan 23, 2008 (1:29 pm)
I have a 05 Sub. and have chirping noise from engine. Had the belt replaced twice and chirp was gone for a while now it is back. What else can we look for?

Replying to: tryn2comeup (Jan 23, 2008 8:07 am) I don't know specifically for your model year, but usually the air suspension isn't available on an LS or LT1/LT2 trim level, is optional on LT3, and standard on LTZ.
#23 of 36 Noise in reverse (2002 Suburban) by godbehere Jun 29, 2008 (1:20 pm)
I have a 2002 Suburban 1500. It has about 84k miles. I makes a noise when you are in reverse but does not make a noise in forward. It sounds like something is rubbing. Any ideas? Replies to this message: jaxkool (Mar 02, 2009 2:32 pm)
#24 of 36 Suspension noise? by ahightower Aug 16, 2008 (6:17 pm)
I got new tires put on today (at Wal-Mart). Just after that, and ever since (dirven about 40 miles today), there is a squeaking noise coming from the front left tire area. I can recreate the sound by gently rocking the vehicle back and forth, in park, engine off. I can't pinpoint it exactly, but it is definitely coming from the left front tire/suspension area. It makes the noise almost continually whenever the vehicle is in motion, even on smooth roads. It is not dependent on braking or accelerating or turning. What do you think it might be? Did they perhaps set their jack on the wrong spot and bend a suspension component? Is it likely a "lube chassis" grease gun sort of job? I hope they didn't do significant damage. I appreciate any advice you might have. Thanks. Replies to this message: arrie (Aug 16, 2008 9:02 pm) ahightower (Aug 17, 2008 8:05 am)

Replying to: ahightower (Aug 16, 2008 6:17 pm) I read about this noise a couple of weeks ago but don't remember where it was in this forum.   That post explained about a this noise coming from the shock absorber and it has to do with some bushing or something like that. That post explained how GM has a TSB on it and how to replace these bushings.   The problem might have started because your shocks probably extended all the way when they lift your car up for changing your tires, i.e. the shock probably moved to its end and caused this noise to appear due to that faulty bushing (or what ever it was).   Wal-Mart guys have nothing to do with this.   Arrie Replies to this message: ahightower (Aug 17, 2008 8:05 am)

Replying to: arrie (Aug 16, 2008 9:02 pm) Thanks Arrie. I sure appreciate the quick responset. And, I re-read my post and regret being so quick to blame Wal-Mart. (For what it's worth, the tires seem great. Very quiet, good handling.) I suspected something similar to what you have described after having slept on it. The noise was much much quieter this morning on the way to church, and as soon as I dropped the wife and kids at home so I could drive back to Wal-Mart, it disappeared completely. Not even the biggest bumps elicit a noise now, and I cannot recreate it by jumping up and down on the running board. I suspect it has "settled" again, or some grease has worked its way back up into there where it had been fully extended. So, unless it reappears, I'll consider the case closed.   Now, regarding that TSB, one thing I did do last night was to log onto mygmlink.com website and search for recalls/TSB. Entered my VIN and nothing was noted for it. I suppose with a TSB they don't publish it, just address it if you have a complaint? And I presume it is not affected by in/out of warranty status? I would like to look up and read that TSB, but I don't suppose they'd do anything at a dealership unless they could re-create the symptom? And I don't want to get stuck with a diagnostic fee and be told everything is fine.
