Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Balancing

Tools Required: Tire balancing machine, digital tire pressure gauge, jack, jack stands
Sub-steps:
1. Remove the wheel covers if applicable.
2. Jack up the vehicle and secure it with jack stands.
3. Remove the wheels and inspect tires for any visible damage.
4. Check tire pressure; adjust to recommended PSI if necessary.
5. Mount the tires on a tire balancing machine and balance them according to specifications.

3. Suspension Component Inspection

Tools Required: Wrench set, socket set, torque wrench
Sub-steps:
1. Visually inspect all suspension components for signs of wear or damage.
2. Use a wrench to check for looseness in nuts and bolts on suspension parts.
3. If any components are worn (e.g., bushings, shocks), replace them with new parts.
4. Torque all bolts to manufacturer specifications.

4. Wheel Bearing Inspection

Tools Required: Torque wrench, jack, jack stands
Sub-steps:
1. Remove the wheel and brake assembly to access the hub.
2. Rotate the hub by hand; listen for grinding noises or feel for roughness.
3. If defective, replace the wheel bearing using appropriate tools.
4. Reassemble the hub and brake assembly, ensuring all fasteners are torqued correctly.
