Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery as a safety precaution.

2. Inspect and Replace Suspension Components

a. Inspect Shock Absorbers

Check for any signs of wear or leakage.
If damaged, remove the bolt securing the shock absorber at the bottom using a socket wrench.
Remove the upper mounting bolts of the shock absorber.
Replace with a new shock absorber and tighten bolts to the manufacturer's torque specifications (typically around 30-40 ft-lbs).

b. Check Bushings and Mounts

Inspect all bushings (control arm, sway bar, etc.) for cracks or deterioration.
Use a socket set to remove any damaged bushings.
Replace with new bushings and ensure they are properly lubricated.
Reinstall and torque to manufacturer's specifications.

c. Inspect and Tighten Loose Hardware

Check all suspension-related bolts and hardware for tightness.
Use a torque wrench to tighten any loose bolts to the specified torque (check the service manual for exact values).
