Drivers Floorboard Slight Vibe

It seems to creep in more on higways when your in 3rd or OD 55-70mphish. I can't be sure if this is coming from the Transfer case stick shake. I do feel the TC stick vibe move back n forth more at higher speeds. Maybe some driveline noise is kicking back up through the stick. Got underneath, and in park that TC makes alot of noise inside. Tranny stick is dead quiet. Steering is dead quiet. Suspension is tight. Truck drives as straight as an arrow. The BF AT look like they are older, but the wear is even. 56k on it now. Looks 100% stock to me. You can also see the Passengers side headrest moving at higher speeds. I had the tires force balanced and it did seem to at least somewhat diminish headrest movement.

Any feedback would be greatly appreciated.

Thanks,

sounds like if it made a little difference when you had the tires balanced that the tires are still a little off , I had to have mine rebalanced 6 , yes 6 times before the idiots finally got it right, good luck

 

could it be a driveshaft slightly off balance?

 

I'm wondering if I have 2 seperate issues. But it's foot numbing gas pedal and footrest. I notice it at lower speeds too, when there is a load on the engine. Is it just normal engine harmony? It goes away as soon as the load is off the engine..coasting. I think maybe the problem just gets exasorbated by higher speeds. Not sure what to think at this point.. My head's in a funk.

Thanks for posting though

 

I had a slight humming and shimmy on my 03 and it turned out to be the winter tires were scalloped a bit causing the shimmy and humm. If your tires are getting up there I would start there if everything is tight as you say. Good luck
