Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack stands, pry bar, and a flashlight.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Inspect and Replace Suspension Components

Lift the Vehicle:
- Use a jack to lift the front or rear of the vehicle as needed, and secure it with jack stands.
Inspect Shock Absorbers:
- Use a flashlight to check for leaks or physical damage on the shock absorbers.
- If they show signs of wear, proceed to replace them.
Replace Shock Absorbers:
- Remove the retaining bolts on the top and bottom of the shock absorber using a socket set.
- Carefully pull out the old shock absorber and replace it with a new one.
- Tighten the bolts to the manufacturer's specified torque value (consult service manual for exact specifications).
Inspect Control Arms and Bushings:
- Use a pry bar to check for play in the control arms and bushings.
- If any components are damaged, remove and replace them as necessary.
Reassemble and Lower the Vehicle:
- Once all necessary components are inspected/replaced, reassemble any removed parts.
- Carefully lower the vehicle back to the ground and reconnect the negative battery terminal.
