#430 of 762 Vibration / Resonance at 40-50mpg and 70-80mph
Nov 27, 2007 (9:42 pm)
I have a 2003 Chevy Tahoe Z71 with just over 120,000 miles on it. For as long as I can remember I've had what can best be described as a sound from the front left wheel-area like i'm on a train. Evenly spaced duh-duhs, like the wheels of the train going over the spaces in the rails. Weird, I know. However, what makes this troubling now is that the noise is associated with a vibration at between 40-50mph and again at 70-80mph.
Seeing that I drive to Boulder, CO about 4x a month from Aspen, I need my truck to drive well. Any thoughts? A friend of mine said it could be the Wheel Bearing. I'm not sure.

I'd suspect a belt in the tire is bad. Swap the tire to the back, and see if the noise moves with it....or stays in the front.

hey, thanks for the msg. I don't its the tire belt. All four tires are brand new, relatively. <1000 miles on 'em. Maybe i'll have them switch them just for the heck of it... thanks.

Well if the problem existed before the tires were changed, then it probably isn't the tire.
You should check the wheel bearing, and the Constant Velocity Joint.
I'd also recommend since they'll be there, at checking that there isn't too much play in the lower ball joint. I had both of mine bad at about 60K miles in older Suburban. A ball joint problem would cause other problems also like alignment and abnormal tire wear.

i have a 2004 tahoe z71 and the speedometer and another gauge both broke 2 years ago and I took it to dealer to have it checked out they said pay $900 and we can fix it. I didn't have that much to drop on a simple problem. Now they tell me it was a defective part! but they won't fix it now! chevy sucks!!!

I have a 2005 tahoe w/ the digital climate control system. It seems to only have 2 settings either 60 or 90. the heat only works with the control set to 90. if i put it at 89 it goes to the coldest setting.
does anyone have any ideas on how to fix?

I have the exact problem with a 2003 Tahoe. Tried replacing the entire heating unit into the dash. No help. Looking for answer.

Found the answer to 2003 Tahoe climate controll problem. Set on 90 heats and 89 and less goes to cold air. No inbetween. Look up from drivers seat to see small plastic in headliner. Looks like small speaker, but is not. Under the headliner is a small sensor type gizmo. Has fan and very small wire with black ball on end. Reminds me of a very small antena. This works with the climate controll system. New part was less then $30.00 new. Plugged it in which resulted in happy ending.
