Tools Required: Floor jack, jack stands
Use a floor jack to lift the vehicle and secure it on jack stands.
Remove the wheels for better access to suspension components.

3. Inspect and Replace Components

A. Sway Bar Links and Bushings

Remove the sway bar link bolts using a socket set.
Inspect bushings for cracks or wear; replace if necessary.
Install new sway bar links and bushings, torquing bolts to manufacturer specifications.

B. Shock Absorbers

Detach the top and bottom mounting bolts of the shock absorber.
Remove the shock absorber from the vehicle.
Install the new shock absorber, ensuring proper alignment and torque specifications are met.

4. Lubricate Components

Apply lubricant to all moving parts and joints in the suspension to reduce friction and noise.
Focus on bushings, mounts, and joints that are frequently subjected to movement.
