Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and set the parking brake.
Gather safety equipment (gloves, safety glasses).

2. Tire Inspection

Sub-steps:
1. Check tire pressure using a tire pressure gauge; adjust to manufacturer specifications.
2. Inspect each tire for uneven wear (look for bald spots, cupping, or blistering).
Tools Required: Tire pressure gauge, inspection light.

3. Suspension Component Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Visually inspect the struts and shocks for leaks or damage.
3. Check all suspension bushings for cracks or deterioration.
4. Wiggle the components to check for excessive movement.
Tools Required: Jack, jack stands, wrench set.

4. Wheel Bearing and CV Joint Check

Sub-steps:
1. Spin each wheel by hand to listen for grinding noises indicating bad bearings.
2. Inspect CV joints for torn boots or grease leakage.
3. If any issues are found, remove the affected wheel and replace the bearing or CV joint.
Tools Required: Socket set, torque wrench.

5. Reassemble and Lower Vehicle

Sub-steps:
1. Reattach any components removed during inspection.
2. Lower the vehicle from the jack stands and torque lug nuts to manufacturer specifications.
Tools Required: Torque wrench.
