Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is off.
If working on the power steering system, disconnect the battery to prevent electrical shocks.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; top off with the manufacturer's recommended fluid if low.
Inspect the fluid for contamination or burnt smell, indicating potential issues.

3. Inspect and Repair Leaks

If leaks are detected, replace the affected hoses or seals.
For a leaking steering rack, consider replacing the unit if necessary.

4. Inspect Steering Components

Raise the front of the vehicle using a jack and secure with jack stands.
Inspect the steering linkage (tie rods, ball joints) for play or wear. Replace any damaged components.
Check the condition of the steering column and U-joints for any signs of wear.

5. Align Steering System

If steering components were replaced, perform a wheel alignment to ensure proper handling and tire wear.
Use an alignment machine to set the camber, caster, and toe angles to manufacturer's specifications.
