Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Suspension Components

Shocks/Struts Replacement:
1. Remove the wheel to access the suspension assembly.
2. Disconnect the upper and lower mounting bolts of the strut.
3. Remove any brake line brackets and sensors attached to the strut.
4. Carefully extract the strut from the assembly.
5. Install the new strut and torque bolts to manufacturer specifications (typically around 50-80 ft-lbs).
Sway Bar Link Replacement:
1. Locate the sway bar links and remove the nuts on both ends.
2. Replace with new sway bar links and ensure they are tightened securely.

3. Lubrication of Bushings

Apply a suitable lubricant to any rubber bushings that may be dry or cracked.
Ensure they are correctly seated in their respective mounts.
