Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working with electrical components (if applicable).

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure that all safety precautions are followed to prevent accidents.

3. Inspect Suspension Components

Visually inspect the shock absorbers for leaks or damage.
Check the sway bar links for looseness or breakage.
Use a pry bar to test the control arm bushings for play or wear.

4. Replace Damaged Components

If any components are found to be damaged:
- Shock Absorbers: Remove the top and bottom bolts securing the shock absorber, replace with a new unit, and torque bolts to manufacturer specifications.
- Sway Bar Links: Remove the worn link and install the new one, ensuring it is tightened to the specified torque.
- Control Arm Bushings: If needed, remove the control arm, replace the bushings, and reinstall, torquing to the proper specifications.

5. Reassemble and Lower Vehicle

Reinstall any removed components in reverse order.
Double-check the tightness of all bolts before lowering the vehicle.
Carefully lower the vehicle back to the ground.
