Solution

1. Preparation

Gather tools and parts required for repair.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery for safety.

2. Inspect and Replace Shock Absorbers

Tools Required: Socket set, torque wrench, jack and jack stands.
Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Remove the wheel to access the suspension components.
3. Remove the bolts securing the shock absorber at both the top and bottom.
4. Carefully remove the old shock absorber and replace it with a new one, ensuring that the orientation is correct.
5. Torque the bolts to the manufacturer’s specifications (consult the service manual for specific torque values).
6. Reinstall the wheel and lower the vehicle.

3. Inspect and Replace Control Arms (if necessary)

Tools Required: Socket set, wrench, torque wrench.
Sub-steps:
1. Inspect control arms for any cracks or signs of excessive wear.
