Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Tire Inspection

Tools Required: Tire pressure gauge, flashlight
Steps:
1. Remove hubcaps or wheel covers if applicable.
2. Use a tire pressure gauge to check the inflation of all tires; adjust to manufacturer specifications.
3. Inspect each tire for cuts, bulges, or foreign objects embedded in the tread.
4. Check tread depth using a tread depth gauge; replace tires if tread is below the recommended level.

3. Suspension Inspection

Tools Required: Jack, jack stands, socket set
Steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Visually inspect the shocks and struts for leaks or physical damage.
3. Check control arms and bushings for signs of wear; replace any damaged components.
4. Wiggle the wheel at 3 and 9 o'clock to check for play in the suspension joints.

4. Wheel Bearing and Drivetrain Check

Tools Required: Multimeter (optional for testing), torque wrench
Steps:
1. Spin each wheel by hand and listen for noise indicative of a failing wheel bearing.
2. Inspect the driveshaft and CV joints for any visible damage or excessive play.
3. Tighten any loose bolts or connections as per specifications.
