Solution

1. Preparation

Park the vehicle on a level surface and secure it with wheel chocks.
Gather tools including a jack, jack stands, lug wrench, and torque wrench.
Disconnect the battery if working on electrical components or drivetrain.

2. Tire Inspection

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Inspect the tires for bulges, cuts, or uneven tread wear.
3. Measure tire pressure using a tire pressure gauge and inflate to the manufacturer's specifications.

3. Suspension Component Check

Sub-steps:
1. Raise the front and rear of the vehicle using a jack and secure with jack stands.
2. Visually inspect shocks and struts for leaks or damage.
3. Check control arms and bushings for any signs of wear or cracking.
4. Shake the wheel to check for play, indicating worn bearings.

4. Drivetrain Inspection

Sub-steps:
1. Check the CV joints and axles for any tears in the rubber boots.
2. Inspect the differential for any signs of oil leaks or damage.
3. If necessary, remove and inspect the CV axle or driveshaft for wear.

5. Reassembly and Reinstallation

Sub-steps:
