Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Tire Inspection

Sub-steps:
1. Remove the wheel covers or hubcaps if necessary.
2. Check tire pressure and compare with manufacturer specifications.
3. Inspect for any visible bulges, cuts, or foreign objects in the tires.
4. Rotate or replace tires if uneven wear is observed.

3. Suspension Component Inspection

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Visually inspect control arms, bushings, struts, and shocks for wear or damage.
3. Wiggle the suspension components to check for any looseness.
4. Replace any damaged suspension parts (e.g., bushings or ball joints).

4. Wheel Bearing Inspection

Sub-steps:
1. Remove the wheel from the affected side.
2. Check the wheel bearing for play by trying to move the wheel up and down.
3. If the bearing is loose or rough, it should be replaced.
4. Use a torque wrench to tighten lug nuts to the manufacturer-recommended specifications upon reassembly.

5. Exhaust System Check

Sub-steps:
1. Inspect the exhaust system from the engine to the tailpipe for loose or damaged components.
2. Tighten any loose clamps or brackets.
3. Replace any damaged sections of the exhaust if necessary.

6. Brake System Inspection

Sub-steps:
1. Remove the wheel and inspect the brake pads and rotors for wear.
2. Ensure the caliper is securely mounted and not loose.
3. Replace worn brake pads or damaged rotors.
