Vibration on floor
My 99 F350 dulley psd has a bad vibration on the drivers floor when it reaches above 30 mph. The trans,engine, and rear end has been serviced. I put the rear on jack stands and brought the engine in drive up to 2500 rpm and the vibration is not their, which makes me believe the problem is in the front end. If someone can please help, my dealership has not been able to. Their is no vibration in the steering wheel. Thanks

Vibration on floor
I had a similar vibration before my front bearings failed. It felt like a loose shock knocking under the driver's feet.
Hope this helps! Keith.

If the truck was supported on the frame, you have changed the driveshaft angle, and therefore the vibration went away/changed. you need to support the axle to properly duplicate the problem.
