Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to ensure safety.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Ensure that the vehicle is stable before proceeding.

3. Inspect and Replace Suspension Components

Sway Bar Links:
- Remove the nuts securing the sway bar links using a socket set.
- Inspect the links for wear; replace if damaged.
- Torque the new sway bar link nuts to the manufacturer's specifications (usually around 40 Nm).
Shocks/Struts:
- Remove the bolts securing the shock absorber or strut assembly at the top and bottom.
- Pull out the shock/strut assembly and inspect for leakage or damage.
- Replace with new shocks/struts if necessary, ensuring to torque the bolts to specifications (usually around 70 Nm for lower bolts and 20 Nm for upper bolts).
Bushings:
- Remove any components blocking access to the bushings (if necessary).
- Use a bushing tool or press to replace worn bushings in the control arms or sway bar.

4. Reassemble and Lower Vehicle

Reattach any components that were removed.
Lower the vehicle back to the ground and remove jack stands.
Reconnect the battery.
