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 Replacement

Sub-steps:
- Remove the wheel covers or hubcaps if applicable.
- Inspect each tire for bulges, cuts, or uneven wear patterns.
- Use a tire pressure gauge to ensure all tires are inflated to the recommended pressure.
- Replace any damaged tires with new ones, ensuring they are of the same specifications as the original.

3. Suspension Component Replacement

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the wheel to access suspension components.
- Inspect control arms, bushings, and struts for signs of wear.
- If damaged, remove the old components using a socket set.
- Install new suspension components, ensuring they are torqued to manufacturer specifications (consult repair manual for specific torque values).

4. Driveshaft and CV Joint Inspection

Sub-steps:
- Inspect the driveshaft for any visible damage or play.
- Check CV joints for tearing or excessive movement.
- If a CV joint is damaged, remove the axle nut and detach the axle from the hub.
- Replace the CV joint or the entire axle if necessary, ensuring proper alignment and torque.

5. Assembly and Final Checks

Sub-steps:
- Reassemble any components that were removed during the inspection.
- Reattach tires and ensure lug nuts are tightened to the specified torque.
- Lower the vehicle and reconnect the battery if disconnected.
