Replying to: rabown (Sep 19, 2008 6:15 pm) That has been a common problem caused by the bug deflector. Buy some window sealant from Checkers and reseal the windshield. |

| I have a 2005 Chevrolet Silverado 1500 (RWD Ext Cab/5.3 V8) and started to notice a popping noise in the vicinity of the center floorboard hump. The rate of the pop doesn't increase or decrease with the engine RPMs and it doesn't increase or decrease when the truck is in gear, parked, or being driven. I opened the hood to see if the noise could be heard from the engine compartment and I listened from underneath the truck, but did not hear anything. Anyone have the same or similar problem? | |
Looking for a solution. The 2002 Sierra 1500 extended cab drives as if all 4 tires are badly out of balance. The problem begins at approximately 40 mph and felt primarily on the drivers side. So far, every experiment seems to aggravate the problem. We have consulted with a tire company, 5 GM dealerships, GM, and no experiment has helped. Considerable attentiion has be given the wheels, tires, drive shaft, mounts, and barrings. GM recommends replacement body mounts and if that doesn't work, then replace the drive shaft. GM does not know how to correct the problem. Has anyone found a solution to this problem which seems to be characteristic of this GM truck?

Replying to: sedaman (Oct 21, 2008 7:02 am) -2 or 4wd? -When did this start? -Some of the dealerships have a vibration tracking device. Costs about $2500 so not all of them have it. Has this been used at any of the 5 dealerships?

Replying to: sedaman (Oct 21, 2008 12:56 pm) Hunter GSP 9700 Most harmonic vibrations start at around 50-55 mph. The fact that yours start at 40 is unusual. The only thing that happens at that mph is the torque converter locks up at 39 mph and driving at that speed had generated some amount of complaints as the engine tends to lug which might be associated with a type of vibration. Not sure if this would be the case as you've had the truck for awhile and would've noticed this sooner if it was a problem. Was anything replaced on the truck prior to this happening?
