My pickup has a high speed vibration, i took the rear driveshaft off and checked u joints, they moved freely and are tight, checked brakes and E brake shoes (rear disk), those are fine, now im stumped, does the front drive shaft on a 00 f150 spin while in 2wd? Any ideas?

Balance the tires? -
Check to see if the vibration is in the steering wheel or not. Rotate tires. If it changes then it's tires/balance. General rule of thumb, if you feel vibration in the steering wheel, its coming from the front, if you feel it in the floor/seat, it's coming from the rear.8.54 @ 159 mph on a 275 drag radial

A simple wheel balance will cure most vibrations. But if that doesn't cure the problem, your problems may go deeper. Begin by cranking the wheels over to the steering stop and looking at the inside of the rim. It's customary to split the amount of the balance weights between the inside and outside of the rim. If a weight (even an old one) has come off, that could be the problem. The weight should leave a clear outline, so you'll know exactly how much is missing. If the balance weight was added recently, you can take it back to the shop for a replacement.Originally posted by Ford Fan View Post
If the vibration is not related to torque, shift into Neutral and let the vehicle coast at the problem speed. Still have the vibration? It's speed sensitive pure and simple. This could be the source of your troubles, even if the wheels are balanced and the tires are good. It's not a powertrain or driveline issue.
