Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, screwdriver set, multimeter, torque wrench.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Power Steering Fluid

Check the power steering fluid reservoir for level and condition.
If low, top off with the manufacturer-recommended power steering fluid.
If fluid is dirty or contaminated, perform a fluid flush:
- Disconnect the return line from the power steering pump.
- Use a suitable container to catch old fluid.
- Refill reservoir with new fluid while turning the steering wheel to cycle the system.

3. Inspect and Replace the Power Steering Pump (if needed)

Remove the serpentine belt using a wrench to relieve tension.
Disconnect the power steering pump hoses and electrical connectors.
Remove the mounting bolts securing the pump.
Install the new power steering pump by reversing the removal steps and ensuring all connections are secure.

4. Check and Replace Tie Rod Ends (if necessary)

Lift the vehicle and secure it on jack stands.
Remove the wheel to access the tie rod ends.
Use a wrench to loosen the jam nut and remove the tie rod end from the steering knuckle.
Install the new tie rod end and tighten the jam nut to the manufacturer’s specifications.
Reinstall the wheel and torque the lug nuts to the correct specification.

5. Inspect and Replace Wheel Bearings (if necessary)

Remove the wheel and brake assembly to access the wheel hub.
Inspect the wheel bearing for play or roughness by rotating the hub.
If damaged, remove the hub assembly and replace the wheel bearings with new ones.
Reinstall the hub and brake assembly, ensuring all components are properly secured.
