Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface, engage the parking brake, and lift the front or rear of the vehicle using a jack. Secure it with jack stands.

2. Inspect and Replace Worn Components

Sub-steps:
1. Remove the wheel to access the suspension components.
2. Inspect sway bar links, control arm bushings, and ball joints for wear.
3. If any components are worn, use a socket set to remove the bolts securing the damaged parts.
4. Replace with new parts, ensuring all bolts are torqued to manufacturer's specifications (usually around 50-80 ft-lbs for suspension components).

3. Check and Replace Shock Absorbers

Sub-steps:
1. Remove the bolts securing the shock absorber at both the top and bottom using a wrench.
2. Replace with new shock absorbers, making sure to align them correctly.
3. Torque the bolts to the manufacturer’s specifications (typically around 30-50 ft-lbs).

4. Reassemble and Lower the Vehicle

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Remove the jack stands and lower the vehicle.
3. Torque the lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs).
