Vibration

I have a vibration in my truck. You can feel it in floor under feet and also in the gas pedal some. You dont feel it all times but it does go away if you let off the gas pedal. It seems to be related to engine speed. Any ideas?

i have vibration in mine also.....something that i noticed is that i went to change my u jints in my 2001 that we had bought(used), and i noticed that my driveshaft was in backwards, so i installed it the right way thinking that was where the vibration was from and that wasnt it.
So i put my truck on stands and put the truck in geaf and looked for bent rims or whatever, and what it turned out being was my driveshaft. The yoke was wobbling around and had play....only would do it when i reached 40+ mph when i let my foot off the gas.

Wheel Bearing, Had the same problem. Put the truck on a jack, and spin the front tire with your hand. Youll probably feel or hear it resisting the turning a bit. Also pull in and out to check for play.

I thought I had a wheel bearing going out. I could feel a vibration thru the pedals and floor board. It turned out to be the serpentine belt. It had split right down the middle.

The bearings are good and the belt looks to be good. Any other ideas would be graet.

Take your wifes makup mirror under the truck and REALLY look hard at all the ujoints and caps on your rear driveline. I was fartin around under the lift about 4 hours into a front end tear down, and noticed a split cap on one of the rear ujoints that you had to have the perfect angle to see. And it was causing my vibrations. Mine were on or off the gas though.

also check the inner bearings where the front axle shafts go into the hub assembly.

mods thus far:
1704 tuner gizmo, BHAF, 4" DP to 5" stack, FPR w.109 shim, disconnected wastegate, plethora of gauges, 10k mod w/ 20k resistor (removed after it jacked up my connector), 17*HPOP (not really), hybrid sticks (I wish), some kinda badass turbo (another lie), mega body damage (that's gospel).

hey dude,just an idea.. check your rear end, at lower speeds can you kinda hear it? like a roar....roar...roar...and it vibrates the floor and steering wheel sometimes and the gas pedal, both my last trucks...f350 7.3's did this, i went over EVERYTHING back to front then relized it was the rear pinion bearing, you may need a stethoscope and just touch the housing where the front pinion bearing is,,see if its loud...just an idea.

05+ coils, 10 Rear diff, box, tailgate, lights, bumper, Full 07 front harley swap...the list is endless.

AS IM RARLEY on here anymore...have a question ?? EMAIL ME dakinbryce@hotmail.com..ill gladly answer any of your questions. OR search me on facebook. ill help out anyway I can !
