Solution

1. Preparation

Gather tools: socket set, torque wrench, fluid catch pan, and a flashlight.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery to prevent accidental activation of electrical systems.

2. Inspect and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check fluid level; if low, top up with the manufacturer-recommended power steering fluid.
Inspect the fluid for contamination or burnt smell; if contaminated, a fluid flush may be required.

3. Check for Leaks

Visually inspect all power steering hoses for cracks or signs of wear.
Examine the steering rack for fluid leaks; if any leaks are found, replace the damaged component.
Clean any spills from the undercarriage to facilitate future leak detection.

4. Inspect Steering Components

Lift the front of the vehicle using a jack and secure it with jack stands.
Check the steering column and universal joints for play or wear; replace any damaged parts.
Inspect tie rod ends and ball joints for looseness; replace if necessary.

5. Reassemble and Torque

If any components were removed, reassemble by following the reverse order of disassembly.
Use a torque wrench to tighten all fasteners to manufacturer specifications.
