Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather all necessary tools and parts.
Disconnect the battery, especially if working on electrical components.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add the appropriate fluid if low.
If the fluid is dirty or contaminated, drain and replace it.

3. Inspect Power Steering Pump

Remove any covers obstructing access to the power steering pump.
Listen for unusual noises when the engine is idling and the steering wheel is turned.
If noisy, replace the power steering pump.
- Disconnect the fluid lines and the pump mounting bolts.
- Install the new pump and reconnect the fluid lines, ensuring a proper seal.

4. Inspect CV Joints and Axles

Raise the vehicle and secure it on jack stands.
Spin the front wheels by hand to listen for any grinding or whining noises.
Check for torn CV boots or signs of grease leakage.
Replace damaged CV joints or axles as necessary.

5. Check Wheel Bearings

Spin the wheel while it's off the ground to feel for roughness or noise.
If bearings are worn, remove the wheel and brake components.
Replace the wheel bearing assembly, ensuring proper torque specifications when reassembling.
