What could it be?

[luv mi hoe]

I have a 96' Tahoe 2-door and the problem that I'm having is that once the truck goes up to 50 MPH the front starts shaking. When I go up to 60 MPH it still shakes but it's a different rattle...almost defening inside.
The weird thing is no matter what speed I'm on, once i let my foot off of the gas, within 5 seconds the rattle is completely gone! If I give it gas while it's slowing down, the rattle picks up again.
Does anyone know what it could be? The wife wants me to get rid of the truck but I love it too much. Advise please....

Have you checked the U joints? how are the tires?

 

[SunlitComet]

you need to check your front end for loose parts. and well as balance and condition of tires.

do you feel the shake in the steering wheel or the seat?

The tires seem fine! all of them are equally & eveny worn and there's no wear in the tires.

I don't really feel the rumbling...It's more of a rumbling sound than somethng that's felt. The only way you can see it is when looking at my side or rear-view mirrors.

Subwoofer?

It's one of your spark plugs going bad and if not its spark plug cable
