Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during electrical inspections.

2. Inspect and Replace Power Steering Fluid

Check Fluid Level: Remove the power steering reservoir cap and check the fluid level.
Fluid Condition: If the fluid is dark or contaminated, it should be replaced.
Replacement:
1. Using a turkey baster, remove old fluid from the reservoir.
2. Fill with new power steering fluid (consult owner’s manual for specifications).
3. Reconnect the battery and start the engine, turning the steering wheel from lock to lock to bleed the system.

3. Inspect and Replace Suspension Components

Tie Rod Ends and Ball Joints:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. With a socket set, remove the wheel for better access.
3. Inspect tie rod ends and ball joints for any visible wear or damage.
4. If damaged, replace with new parts and torque to manufacturer specifications.

4. Check and Replace Wheel Bearings

Wheel Bearing Inspection:
1. Spin the wheel and listen for roughness or grinding.
2. If there is noise, remove the wheel bearing assembly.
3. Replace with a new wheel bearing and ensure proper greasing.
4. Torque bolts to manufacturer specifications.

5. Inspect Brake Components

Brake Pad and Rotor Inspection:
1. Check brake pads for wear; replace if less than 3mm thickness.
2. Inspect rotors for scoring or damage; machine or replace as necessary.
3. Reassemble all components and ensure all bolts are torqued properly.
