1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery for safety when working on electrical components.

2. Inspect and Tighten Suspension Components

Tools Required: Socket set, torque wrench.
Inspect all suspension bolts, bushings, and mounts for any signs of looseness or damage.
Tighten any loose bolts to the manufacturer's specified torque settings.
Replace any worn bushings or mounts as necessary.

3. Replace Worn Shock Absorbers (if applicable)

Tools Required: Jack and jack stands, socket set, spring compressor (if needed).
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel for access to the shock absorber.
