Chevrolet Avalanche Noise and Vibration
I have a 07 Av LTZ and have had a problem since day one with it. Its a drivers side wind noise coming from either the drivers side door or the drivers side rear door. Starts about 55 mph and gets increasingly worse as the speed increases. It doesn't leak when raining out or going thru the car wash. But, the damn wind noise when cruising down the highway just sucks and is annoying as hell.
Anyone had this problem and is there a fix?

I had the same problem with my '05. The molding at the top of the door was creased slightly. Sometimes when the window was rolled up it would create a small gap not enough for water to leak in but enough to make that iritating noise. I straightened out the molding and have not had a problem since.
Hope this helps.
I have one and it as a lot of air noise I have taken it back 2 times and the are telling me that it is within tolerances. Any ideas it seems that it is an excuse.
Thanks

The following is a list of some of the things they have done to try and reslove the issues as of 01/09/07 Interm Shaft Exercise/Stroke 01/31/07 Crossmember front suspension replace, 03/15/07 Pump assy , power steering - replace, 03/15/07 Hanger and or clamp exhaust system replace, 05/25/07 Lubed balljoints, tierods, pitman, idler arm, service tech still noted hearing issues they showed me bulletin # 03-08-61-002h AGAIN, they then removed the front crossmember and lube and added washers performed road test then found bullentin #06-08-61-003A and then they installed body mounts.
Today the service department checked my truck again and of course was quick to say NOW I am out of warrenty. After long debate and calling Chevy Customer service and opening a case they are going to fix the issues that were long reported BEFORE the warrenty expired. Now they are saying they are replacing the Interm Shaft (instead of just exercising it like the did in Jan 2007) and they are going to re check the suspension.
My advice if you are having issues keep taking it in, Keep getting it noted and if the issue is not resloved to your satification call Chevy Customer Service at 800-222-1020. That way when you are out of warrenty it showes you were trying to get it resloved when it was still in warrenty.
Cross your fingers that this time when I get it back it will be repaired (I HOPE) and no more Bullentins
Take a rubber mallet to the catalytic. If it rattles, there's your problem.
You may also want to check the various fittings/connections to see if anything is loose. I've had rattles that I was SURE are suspension, but it was just a d-shackle swinging when I applied brakes/gas.
Have you had any maintenance or mods done recently?

Secondly, does the sound change with increase or decrease with speed or is that clicking constant, regardless of speed? I'd check to see if you have anything wrapped around the driveshaft. Can you tell if it is coming from the front or back? Have you looked in the engine compartment to make sure the fan is all intact?

Have slight vibration at idle and when reached 40 mph.
Had Tranny and Torque converter checked. They are fine.
Engine and transmission mounts were replaced.
Universal and CV joints replaced a while ago.
The mechanic is now saying that vibration could be internal to the engine.
Any suggestions.
Best,
