Solution

1. Preparation

Gather tools and materials.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Tire Inspection and Adjustment

Tools Required: Tire pressure gauge, air compressor, torque wrench.
Check each tire's pressure using a tire pressure gauge and adjust to the manufacturer's specifications (typically found on the driver’s door jamb).
Inspect tires for uneven wear; replace if necessary.

3. Suspension Component Inspection

Tools Required: Jack, jack stands, socket set, torque wrench.
Lift the vehicle using a jack and secure it with jack stands.
Inspect the struts and shocks for any signs of leakage or damage.
Check the bushings for wear or tears; replace if degraded.

4. Shock Absorber Replacement (if needed)

Tools Required: Socket set, torque wrench, spring compressor (if applicable).
Remove the wheel to access the strut assembly.
Disconnect the strut from the upper mounting points and lower control arm.
Use a spring compressor to safely remove the spring from the strut (if applicable).
Install the new shock absorber and reassemble in reverse order, ensuring to torque all bolts to manufacturer specifications.

5. Final Assembly and Lowering

Reinstall the wheel and lower the vehicle from the jack stands.
Torque the wheel lug nuts to the specified value.
