Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted if needed.
Disconnect the negative battery terminal to avoid electrical issues.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir (usually near the engine).
Remove the cap and check the fluid level; top off with manufacturer-recommended fluid if low.
Inspect fluid for contamination (dark color or particles).

3. Inspect Power Steering Pump

Locate the power steering pump and check for any leaks or damage.
With the engine running, listen for unusual noises indicating pump failure.
If the pump is faulty, proceed to replace it.

4. Examine Steering Column and Rack

Remove any under-dash cover panels to access the steering column.
Inspect for binding or interference in the steering column.
Check the steering rack for proper alignment and movement; replace if binding is evident.

5. Replace Worn Components

If any bushings or joints are found to be worn, remove and replace them.
- Tools Required: Socket set, wrench set, tie rod separator, torque wrench.
- Use manufacturer specifications for torque values during reassembly.

6. Refill and Test the System

After repairs, refill the power steering fluid if necessary.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Recheck fluid levels and top off if needed.
