Solution

1. Preparation

Tools Required: Socket set, wrench set, OBD-II scanner, power steering fluid, cleaning supplies, and safety gloves.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If the fluid is low, top it up with the manufacturer-recommended power steering fluid.
Inspect the fluid for contamination (dark color or debris); if contaminated, proceed to the next step.

3. Flush the Power Steering System

Tools Required: Fluid extraction pump, new power steering fluid.
Use the extraction pump to remove old fluid from the reservoir.
Refill the reservoir with new power steering fluid.
Start the engine and turn the steering wheel from lock to lock to circulate the new fluid.
Repeat the extraction and refill process until the fluid appears clean.

4. Inspect Steering Components

Check the steering column and universal joints for play or binding.
Inspect the tie rod ends and ball joints for wear; replace any worn or damaged components.
Lubricate any accessible joints with appropriate grease to reduce friction.

5. Check Electric Power Steering Motor (if applicable)

Use a multimeter to check the voltage supply to the electric power steering motor.
Inspect wiring and connectors for damage or corrosion.
If the motor is faulty, replace it with a new unit following the manufacturer's specifications.
