Park the vehicle on a flat surface and engage the parking brake.
Gather safety equipment (gloves, safety glasses).

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure with jack stands to ensure stability.

3. Inspect and Tighten Suspension Components

Tools Required: Socket set, torque wrench
Check all suspension bolts and nuts for tightness.
Torque specifications should be followed; typically, suspension bolts range from 30-85 ft-lbs depending on the component.
Tighten any loose components.

4. Replace Worn Parts

Inspect shock absorbers for leaks; if leaking, they need replacement.
Parts Required: New shock absorbers (if needed), sway bar bushings or links (if worn).
Remove the old shock absorbers by unbolting them from the top and bottom mounts.
