Suburban Seems to Vibrate A Lot

[2004Suburban]

Hello,

I recently purchased a 2004 Suburban and notice that the entire vehicle vibrates when sitting in traffic. It is not stalling or running rough, it just seems to vibrate more than at other times when stopped in traffic, in or out of park. I can feel it through the steering wheel and the brake pedal. Is this normal for these trucks?

Welcome. No I would say thats not normal. 04 you should be able to put a glass of water on intake and barely get a ripple in water I would say somethings a miss on the tune up side. I would have it on scanner to check parameters are ok. (There maybe a baseline software update.)

I had the car checked out by a mechanic and he said everything was normal. I don't think he did a diagnostic on the computer so I am not sure.
Thanks

The vibration seems to be the engine running rough. What I feel through the floor boards and pedals is exactly how the car is running. I pot my hand on the engine and it seems to be the cause of the vibration. At 50,000 miles, should I consider a complete tune-up?
Thanks

At this point you don't really have much choice. Unless you want to wait till your teeth start rattling in your head or the truck quits on you, whatever comes first. Just kidding.
Suburban is already chewing thru gas it doesn't need any more help

Not stalling or running rough, hm

Transition maybe, loose fly wheel bolts would cause a vibration in a case like this. Maybe. Or a flywheel out of balance.

Just a thought. I have been known to be wrong, once.

Good luck, because it could also be just a plug wire , but a misfire would show up on the tack and the idle would be rough.

Thanks for the responses. I am trinyg to figure out how to describe the vibration. It is a high frequency low intensity vibration. It happens in or out of gear. It makes the bottom of my feet tingle as it come through the floor boars and the whole truck vibrates the same way. If I put my hand on top of the dash board I can feel it.

Thanbks again for the responses.

Broken motor mount?

i would say a tuneup and look at the motor mounts but at 50,000 they should be good. maybe a slight vaccume leak?.....mike

Yeah, I re-read, it's likely NOT the motor mounts. I'm used to older vehicles and I've experienced this before from a broken one.
