Have the tires checked for being round. You can balance a square block but it won't roll smoothly.
bad wheel bearing
== == As the car speeds up the unbalanced wheels start to wobble. The force of the wobble is transferred to the cars body through the steering mechanism. You would feel the shaking first in the steering wheel. It becomes more pronounced as you pick up speed. == == * Front end need's religning, bad tires or tie-rods. * Tires are low in air.
Check for worn steering or suspension parts i.e. Idler arm, Pitman Arm, Tie rod ends, Ball joints, etc.
Your issues could be caused by numerous things associated with the front steering on your vehicle. It is best to have it inspected by a mechanic. A tire shop would be the cheapest and would be able to fix any problems.
Tires bad or out of balance.
Not running on all cylinders? Bad harmonic balancer?
Bad mount on the steers, worn/loose/damaged steering components, axles out of alignment.
It is most likely due to a loose power steering belt. If the steering wheel is hard to turn at speeds slower than 40mph or it gets harder the more you turn it and the squeaking noise happens when you turn the wheel, then you need to check the tension on the power steering belt.
Loose or worn out power steering drive belt. Usually this is a loose or worn belt on the power steering pump. The pump works its hardest when the vehicle is parked or at low speeds so if there is a belt issue, it will happen then.
I would start with wheel balance but the front end steering and suspension needs to be checked also.
Figuring out what the cause of the problem is would be the place to start.
i would check the brake rotors for warping if it gets worse when pressing the brakes
