I've been noticing a vibration in the steering wheel and shift lever of the '03 HO 6 speed 3/4 Ton truck and I'm trying to track it down. The vibration occurs at idle while not moving so I know it's related to either the engine or one of the rotating parts attached to it such as the power steering pump, alternator etc. I took the truck to the dealer this morning and it turns out that a new truck we went and started had the same vibration so it must be typical for these trucks. I would have bet a rotating part was out of balance but I guess not. Does anyone out there have any information on this? The truck has 15,000 miles on it and I would have bet money I wasn't getting the vibration in the steering wheel for the first 14,000 miles but the fact that the new truck has the same vibration has got me stumped. The engine itself appears to be running smoothly which leads me to think it's a different rotating part.
