Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety warning: Disconnect the battery to prevent electrical issues during repairs.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove wheel covers or hubcaps if applicable using a flathead screwdriver.
2. Loosen the lug nuts slightly before lifting the vehicle with a jack.
3. Lift the vehicle using a hydraulic jack and secure it with jack stands.
4. Fully remove the lug nuts and take off the wheels.
5. Inspect tires for uneven wear; replace if necessary.
6. Reinstall wheels, hand-tighten lug nuts, lower the vehicle, and torque lug nuts to manufacturer specifications (usually around 80-100 ft-lbs).

3. Suspension Component Inspection and Replacement

Sub-steps:
1. With the vehicle lifted, visually inspect shocks and struts for leaks or damage.
2. If necessary, remove the damaged strut or shock absorber using a socket set (typically requires 14mm-18mm sockets).
3. Install new shocks or struts by reversing the removal process. Ensure to torque the bolts to the manufacturer specifications.
4. Check and replace any worn bushings or mounts.

4. Wheel Alignment
