I have the AWD 2001 Eddie Bauer. When accelerating through 55 mph the car vibrates like you are running over rumble strips. It stops immediately, but will also sometimes do it coming down in speed through the 55-60 mph range. It is less noticeable when accelerating hard. A friend said this may be the AWD system kicking the front wheels off?
Any advice such as guesses on the problem, possible solutions and most importantly the cost of the solutions would be greatly appreciated.
If not AWD, check to see if your front wheels are balanced...any tire shop can do that for you. That would be the cheapest first suggestion.
Check your u-joints.
Thanks. I was told that this could also be caused by the torque converter going in and out of overdrive. I put some shudder stop in, and we will see.
Check your suspension, the Eddie versions had the air suspension, it could be as simple as the compressor filling the suspension. Whatever it is, it would be best to pass through a ford dealership, the expedition is a hard vehicle to diagnose, especially the package versions.
did u ever find out problem with expedition i have the same problem when accelerating it does the vibration but when just cruising it doesnt thanks
That is called torque converter shudder. It happens when the truck shifts into overdrive, so the timing of when this happens depends on acceleration, speed, and the incline or decline of the road. So don't expect it to happen at any given speed. My car has been doing it for about 3 years and so far it has been nothing but a little annoying. Hasn't gotten any worse or caused any damage to the car. Not saying it can't, it just hasn't done it to mine. Quite an expensive repair. Figure $2K minimum.
