Driver's side wheel bearings, greased

Sounds like a bad wheel bearing.

could be wheel bearing ,could be cv joint could possably be bushings in suspenion.

Variable Effort Steering System Description and Operation
The Variable Effort Steering (VES) system or MAGNASTEER® Varies the amount of effort required to steer the vehicle as vehicle speed changes. At low speeds, the system provides minimal steering effort for easy turning and parking Maneuvers. Steering effort is increased at higher speeds to provide firmer steering (road feel) and directional stability. The Electronic Brake Control Module (EBCM) controls a bi-directional magnetic rotary actuator located in the steering rack and pinion. The EBCM varies the steering assist by adjusting the current flow through the actuator to achieve a given level of effort to steer the vehicle. The VES system accomplishes this by adding or subtracting torque on the input shaft to the rack and pinion. The main component of the system is an electromagnetic actuator, which consists of a multiple-pole ring-style permanent magnet, a pole piece, and an electromagnetic coil assembly. The VES system uses the ABS wheel speed sensor inputs to determine vehicle speed. When the EBCM senses wheel speed, it commands a current to the VES actuator that is most appropriate for each speed. The EBCM commands current from negative two amps to positive three amps to the actuator, which is polarized. At low speeds, a negative current is commanded, which assists steering. At medium speeds no current is commanded and steering is assisted by hydraulics only. At high speeds, a positive current is commanded, which creates steering resistance. Ignition voltage and ground are provided through the EBCM. The EBCM has the ability to detect malfunctions in the actuator or the circuits to the actuator. Any malfunctions detected will cause the system to ramp to zero amps and steering will be assisted by hydraulics only and setting a DTC.

The Magnasteer® system is a speed-dependent power steering system. The Magnasteer® system provides power assist at varying levels depending on need.
A bi-directional magnetic rotary actuator in the steering gear adjusts the amount of torque (driver effort) necessary to turn the steering wheel.
The Magnasteer® is controlled through the ABS module and varies the torque by adjusting the current flow through the actuator.
The amount of adjustment will be directly related to the vehicle speed. The controller receives speed-related input signals from the vehicle speed sensor.
For more information on Magnasteer® refer to Variable Effort Steering System Description and Operation

Is the vehicle driveable ? The steering wheel is connected to the wheels

Sounds like it's stuck on full assist .

Sounds like wheel bearing going out.




Performance Air Intakes

If it happens when the steering wheel is being turned left or right when parking, it could be dry tie rod ends. They will have to be replaced and greased up well to get rid of the sound. This happened to my dad's 1998 Ford Taurus.

Yes. It could be the wheel bearing, but more likely your wheels need to be balanced. As far as the squeaking goes, make sure the ball joints and tie rods are greased (if possible). The squeaking could also be coming from the brakes.

There is nothing to grease. Someones playing with your head. There was a tech bulletin out, on the steering squeeking. I would flush the power steering fluid. I have a 2004. Let us know from time to time how it's doing

Sounds like you might have ball joint problems.This usually happens when they are not greased.Some of these models do not have grease zerk`s.If it does then you can try greasing them but they might be plugged with rust.I would grease the whole front suspension.Hope this helps.Good luck.

If WD-40 got on belt, and squeak went away for a while, it may just need a new belt. The humming noise sounds like a worn wheel bearing that should be checked and replaced if needed. If squeak goes away when you push slightly on brake pedal, it may be rotor on same side as wheel bearing making the noise due to slight shifting of rotor because of worn bearing.You can try swapping tires on front from one side to other to confirm it isn't tire problem as well. If noise shifts to other side, then it's a tire.

you need to get grease into pittman arm there is no grease fitting so get a needle fitting for your grease gun and poke thru the rubber ive done twice on 97 f150s and fixed the problem
