Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Lift the Vehicle

Use a hydraulic jack to lift the front and rear of the vehicle.
Secure with jack stands to ensure safety during the repair.

3. Inspect and Replace Suspension Components

A. Control Arm Bushings

Inspection: Check for cracks, tears, or excessive wear.
Replacement:
1. Remove the wheel using a socket set.
2. Unbolt the control arm from the chassis and the steering knuckle.
3. Replace the bushings with new ones.
4. Reinstall the control arm and torque to manufacturer specifications (typically around 50-70 Nm).

B. Sway Bar Links

Inspection: Look for any play or damage in the sway bar links.
Replacement:
1. Remove the sway bar link using a wrench and socket.
2. Install the new sway bar link and tighten to the specified torque (usually around 30-40 Nm).

C. Shock Absorbers

Inspection: Check for oil leaks or physical damage.
Replacement:
1. Unbolt the top and bottom of the shock absorber.
2. Remove the shock and replace it with a new unit.
3. Torque the bolts to the manufacturer's specified values (typically around 30-50 Nm).

4. Reassemble and Lower the Vehicle

Reinstall the wheel and lower the vehicle from the jack stands.
Tighten the lug nuts to the specified torque (usually around 120 Nm).
