My 2003 ford explorer v8 have a vibration above 55mph for over a year now, and it worsens. Over the time I replaced both front wheel bearings, both rear wheel bearings, rear drive shaft U-joints, front left axle shaft , tires, rims, brakes, ball joints. And so on. Still have that vibration that looks to me like a misbalanced shaft somewhere both I just cant figure out where it is! I've tried to remove the front propeller shaft between the transfer case and front diff and the rear drive shaft also. Still have the vibration. Vibration does'nt get worse on 4wd.

Check for play in the steering rack and tie rod ends.

SOURCE: vibration at above 85 km/h

DO U HAVE A 2 PIECE DRIVE SHAFT? IF SO REPLACE THE CENTER SUPPORT

SOURCE: When slowing to a stop, a vibration begins at

Yes it is very possible.Lift the hood ,have someone stand to one side and watch the engine.Put left foot on the brake,and press the accelerater with the car in DRIVEand bring up the revs slowly.Then repeat with the car in REVERSE.The engine should not move more than an inch or so in either direction.I have seen bad engine mounts let an engine move back and forth six inches by doing the above .BE CAREFULL!!! make sure your foot is down on the brake 100%. Good Luck

Have you had all the wheels balanced? Have you checked for a bent axle?

SOURCE: rotated & balanced tires. new

You will need to check things logically. Run the truck in the air and note where the vibration is at. Take the wheels OFF and put a few lug nuts to hold the rotors on, take the truck to 45mph or whatever the vibration is the worst. is it still there? if its gone, check wheels/ tires. if its still there, check rotors, axles. A drive shaft will make a rapid vibration at low speeds since it turns 3 to 4 times faster than the wheels. does it vibrate on or off the gas? Can you power through the vibration like go 60 and then coast back through? You have replaced a lot of parts that would not cause vibrations. Are you just changing parts willy nilly or is someone actually checking and verifying that these parts really bad?
