Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar.
Ensure the vehicle is parked on a level surface, and the engine is off.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a jack to raise the front or rear of the vehicle.
Secure with jack stands for safety.

3. Inspect and Replace Worn Components

Suspension Components Check:
- Examine the control arms, bushings, and ball joints for wear.
- If any components are damaged:
  1. Remove the wheel for better access.
  2. Use a socket set to unbolt the damaged component.
  3. Install the new part and torque to manufacturer's specifications (typically around 30-50 ft-lbs for bushings).
Sway Bar Links Replacement:
1. Locate the sway bar links and inspect them for damage or looseness.
2. Remove the old sway bar link by unbolting it with a socket set.
3. Install the new sway bar link, ensuring it's tightened to the correct torque specification.

4. Shock/Strut Replacement (if necessary)

If shocks or struts are found to be leaking or worn:
1. Unbolt the shock/strut assembly from the top and bottom mounts.
2. Remove and replace with a new shock/strut, ensuring correct orientation.
3. Torque the new shock/strut to the specified values (usually around 15-30 ft-lbs at the top mount).

5. Reassemble and Lower the Vehicle

Reinstall the wheel, and torque the lug nuts to the manufacturer's specification (typically around 80-100 ft-lbs).
Carefully lower the vehicle to the ground.
