Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery if electrical components will be removed.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels to gain access to the suspension components.

3. Inspect and Replace Shocks/Struts

Inspect: Check the shocks or struts for leaks and damage.
Replace:
- Remove the upper mounting bolts using a socket set.
- Detach the lower end from the control arm.
- Install the new shock or strut by reversing removal steps. Torque upper bolts to manufacturer specifications (typically around 20-30 ft-lbs, check service manual for exact values).

4. Replace Sway Bar Links and Bushings

Inspect: Check for signs of wear or separation.
Replace:
- Remove the bolts connecting the sway bar link to the control arm and sway bar using a socket set.
- Install new sway bar links and torque bolts to specifications.
- Replace bushings if necessary.

5. Reassemble and Lower the Vehicle

Reinstall the wheels and lower the vehicle to the ground.
Torque lug nuts to manufacturer specifications (usually around 75-85 ft-lbs).
