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 to prevent electrical issues during inspection.

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench
Check tire pressure; inflate to manufacturer specifications if low.
Inspect tires for bulges, punctures, or uneven wear.
If tires are damaged or worn unevenly, replace them with new tires of the same size and rating.

3. Suspension Component Inspection and Repair

Tools Required: Socket set, torque wrench, pry bar
Raise the front or rear of the vehicle using a jack and secure with jack stands.
Visually inspect the struts and shocks for leaks or damage.
If any components are worn or damaged:
- Remove the affected component: Use a socket set to remove bolts and detach the strut or shock.
- Install the new component: Position the new strut or shock and hand-tighten bolts. Torque to manufacturer specifications.

4. Wheel Bearing Inspection and Replacement

Tools Required: Bearing puller, torque wrench, socket set
Spin the wheel and listen for grinding noises indicating bearing failure.
If bearings are faulty:
- Remove the wheel: Use a lug wrench to remove wheel lug nuts and take off the wheel.
- Replace the bearing: Use a bearing puller to remove the old bearing and press in a new one. Ensure proper installation and torque to specifications.
