Vibration when driving, especially going around curves. I thought it was because one of my tires was low, but even after filling it with air, the vibartion still exists. It seems to be coming from right side.

Its possible, especially if the noise changes with the speed of the car.

have your tire balance checked , could be rear tire or tires out of balance

sounds like you have a bad wheel bearing, does sound change going around curves ?

Try to do your inflations when the tires are as close to cold as possible, ie: at the closest practical gas station. The further you've driven the more they will warm up. The tire pressure spec. on the sticker in door well is cold pressure. In a pinch when putting in air after driving a "fair" distance, go 2~4 lbs. over, and then recheck when cold.

Also, how good is your gauge? Are you using your own, or the gas station's, or just that funky thing on the pump hose?

Also, consider bumping them up, say to around 40 lbs (verify the max pressure indicated on the sidewall is still higher, likely 44). This will be more likely to rule out measurement inaccuracies, and improve your mileage as well. The only downside is a harsher ride.

Please check for the following conditions:
* Low tire pressures. Raise the tire pressure to a "recommended" setting, preferably close to or at the tire's maximal pressure rating.
* Perform a four wheel alignment and look for signs of unusual tire wear.
* Add additional insulation to the rear passenger and cargo area of the vehicle.
* Check for a defect in the rear control arms as identified in service bulletin 08-001 affecting primarily 2006 and 2007 models. This defect is responsible for abnormal tire wear, noisy operation and even responsible for poor directional tracking at highway speeds.


Keep us updated; hope helps.

High speed steering wheel vibrations and wobbling are almost always due to an unbalanced tire. Start there, cheap, and then move onto more expensive front end part repairs. If you have those silly mag type big wheels which collect and hold gunks of ice in them, then this is what you can expect.

CHECK POWER STEERING FLUID IT COULD BE TOO LOW.OR YOU HAVE INCORRECT TIRE PRESSURE.LACK OF LUBRICATION AT STEERING JOINTS.YOUR FRONT END OUT OF ALIGNMENT.YOU COULD HAVE A FAULTY POWER STEERING PUMP.OR YOU HAVE A LOT OF AIR IN POWER STEERING SYSTEM.YOU HAVE TO BLEED AIR OUT OF POWER STEERING PUMP.CHECK POWER STEERING PUMP HOSES.MAKE SURE.NONE ARE LEAKING OUT FLUID.

If you get a bad vibration in your steering wheel at low speeds without braking it is either a bad tire or a bad rim. If you get a vibration at speeds around 45-50+ and goes away you probably have a balance issue. If the vibration only occurs while braking then your rotors are warped. If low speeds it shakes i'd take it to a shop to check your tires.

It sounds like a possible bad front wheel bearing they will make like a humming or growling noise.The pull could be air pressure a little lower in the right front tire than the left front check the air in all tires and if pull is still there take the left front put it on the right front and put the right front tire on the left front.Sometimes tires get what they call radial pull and that will fix it or make it go the other way if it goes the other way either get new tires or put the back tires on the front of the vehicle and put the front tires on the back.

if the noise isassociated with "wheel speed" then it is in the rolling parts... axle hub bearing brake rotor caliper wheel or tires...if it goes away on right turns then you are unloading or separating the issue then...so a hub /wheel bearing /axle issue is most likely...does your brake pedal pulse when you feel it..(riding the brake while driving)..does the steering wheel shimmy ?

Sounds like the problem is it's a FORD>
