Steering wheel shake at highway speeds, front end inspected - no obvious problems, wheels rebalanced, alignment checked & corrected. Steering wheel still shakes, what next?

Go get your tires balanced and have them check your front end,may need a front end alignment.

Check wheel balance.

Ty, first off, do you feel the vibration in the steering wheel? Is it in the steering wheel & front end? I will assume that the tires were inspected and determined to be ok. Sometimes, the shop may have a rookie do the basic inspection and then have an experienced tech come in if there seems to be an issue. The problem with this is that the ford suspension needs to be "loaded" in order to properly inspect for loose components. That means that they would have to either jack the front suspension on an alignment rack from the control arms or use a jack stand under the control arm.. If the vibration is only in the front end and tires are good. It sounds like there may be an issue with a ball joint or control arm bushing. Something along those lines.. More info needed.

Have a front end suspension check done to eliminate any worm ball joints -shockies- worn suspension rubbers-- steering problems. If ok have a wheel alignment done and have the rear end aligned first as it affects the front alignment. The violent wobble is castor wobble and indicates negative castor possible from sagging suspension springs. The camber is out at that results in the car following every dip in the road. The camber has to work in conjunction with the toe-in measurement and if the 2 are not correct then you will have problems.

Looseness in the front end or a tread separation in the tire. This is extreme but you get the idea if there is a bulge near the side of the tire even a tiny one

These are typical speeds for wheel balancing problems to make themselves obvious. Have you had the wheel balancing checked?

Somethjng is not right with the front suspension of you car. Might be a bent part, something is wear out, or loose. This is dangerous and your tire will create bias, so will cost you more. This car needs a front suspension inspection, and alignment check. We do this service at our dealership 4 wheel alignment $75. GM charge $75 for front wheel alignment, parts extra. Any suspension repair shop can give you a good answer.

This could be an alignment problem in the front or rear or both. Have a 4 vwheel alignment done and the problem should end if the front and rear suspension checks out fine.

It sounds like you may have more than one problem here. First I would investigate Front End Alignment and ALL Steering/Suspension components for excessive wear and/or looseness. Second I would Inspect the Brake Rotors and Pads for uneven wear. Third I would check the Tires for uneven wear and balance. Many things can cause these symptoms: Worn out Ball Joints, defective Shock Absorbers/Struts. Worn out Tie Rod Ends, Idler Arm, even the Steering Gear Box can be part of the problem. Brake Rotors and Tires can be out of Balance with either one causing the problem over 60 MPH. I strongly suggest having your vehicle inspected by an ASE Certified Front End and Brake specialist immediately. It is very dangerous to drive a vehicle with these symptoms.

I had the same problem and it was a small shock sitting horizontally called the steering stabalizer your something close to that. Eazy fix.
