Engine/Transmission (1998.5 - 2002) Floor vibration starting at 70mph

[cmckinney]

Hey guys I installed a 2. 5 front coil lift on my truck this past week and I noticed that at exactly 70mph on my speedometer I start to feel a vibration in the floor of the truck. I don't usually drive above 70mph so I never noticed before the lift. Anyone have an idea of what would cause the vibration in the floor? Front drive shaft possibly?

A floor vibration tells me that you have something wrong with your rear tires or driveline. Normally anything front axle or steering related get's transferred to the steering wheel. You could start rotating tires and see if the vibration follows you. Check u-joints too and anything else that might be loose. All too often once a suspension is altered, things start to show up that you never noticed before, and they can be difficult to track down.

The flap on the front of the engine was causing a vibration in the front of my truck. I moved it so that it did not hang down and the vibration is less. Look to me that if I removed the flap no vibration would occur.
