Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Tires (if necessary)

Sub-steps:
1. Remove the wheel covers (if applicable) using a flat-head screwdriver.
2. Loosen lug nuts using a lug wrench.
3. Lift the vehicle using a jack and secure it with jack stands.
4. Remove the wheel and inspect the tire for bulges, cracks, or uneven wear.
5. Replace tires if any damage or excessive wear is found.
6. Reinstall the wheel, hand-tighten lug nuts, lower the vehicle, and torque lug nuts to manufacturer specifications.

3. Inspect and Repair Suspension Components

Sub-steps:
1. Use a socket set to remove any covers or shields obstructing access to suspension components.
2. Visually inspect shock absorbers and struts for leaks or damage.
3. Check control arms and bushings for wear or play.
4. Replace any worn or damaged components with OEM parts.
5. Reassemble any removed components and torque to specifications.

4. Inspect Wheel Bearings

Sub-steps:
1. Lift the vehicle and remove the wheel as described previously.
2. Check for play in the wheel bearing by moving the wheel up and down and side to side.
3. If play is detected, carefully remove the hub assembly and replace the wheel bearing.
4. Reassemble the wheel hub and wheel, ensuring proper torque settings.
