1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the battery to prevent any electrical issues.

2. Raise the Vehicle

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

3. Inspect and Replace Suspension Components

Control Arms:
- Remove the bolts securing the control arm using a socket set.
- Inspect the bushings for wear; replace if torn or cracked.
- Reinstall the control arm with new bushings; torque bolts to manufacturer specifications (typically around 70-80 Nm).
Shock Absorbers:
- Remove the top and bottom mounting bolts of the struts.
- Inspect for leaks; replace if necessary with OEM or equivalent parts.
- Torque the mounting bolts to specifications (approximately 30 Nm for the top, 120 Nm for the bottom).
Sway Bar Links:
- Remove the bolts securing the sway bar links.
- Inspect the rubber bushings; replace if damaged.
- Install new sway bar links and torque to specifications (usually around 40 Nm).

4. Reassemble and Lower Vehicle

Recheck all connections and ensure everything is secured.
Lower the vehicle back to the ground and reconnect the battery.
