Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery for safety.

2. Inspect Power Steering Fluid

Locate the power steering reservoir and remove the cap.
Check fluid level; if low, top up with the recommended fluid type (refer to owner’s manual).
If fluid is dirty or contaminated, proceed to replace it.

3. Replace Power Steering Fluid (if necessary)

Use a fluid extractor to remove old fluid from the reservoir.
Refill with new power steering fluid, ensuring it meets OEM specifications.
Start the engine and turn the steering wheel from lock to lock to bleed air from the system.

4. Inspect and Replace Wheel Bearings (if necessary)

Raise the vehicle using a jack and secure with jack stands.
Remove the wheel to access the hub.
Check for excessive play in the wheel bearing by moving the wheel up and down.
If worn, remove the old bearing using a bearing puller and install a new bearing, ensuring proper torque specifications for the retaining nut.

5. Inspect and Replace Tires (if necessary)

Check for uneven wear patterns; if found, replace the affected tires.
Ensure proper alignment and balance after tire replacement.

6. Check and Replace Suspension Components (if necessary)

Examine control arms and bushings for wear; replace as needed.
Use a torque wrench to tighten new components to manufacturer specifications.
