Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lift it using a jack and jack stands.
Disconnect the battery to avoid electrical issues during the repair.

2. Replace Shock Absorbers/Struts (if worn)

Tools Required: Socket set, torque wrench, spring compressor (if needed), pry bar.
Remove the wheel to access the suspension components.
Disconnect any electrical connectors from the shock absorber/strut assembly.
Unbolt the top and bottom of the shock absorber/strut assembly.
If applicable, use a spring compressor to safely compress the spring before removing it from the strut assembly.
Install the new shock absorber/strut by reversing the removal steps, ensuring all bolts are torqued to manufacturer specifications.

3. Replace Sway Bar Links/Bushings (if damaged)

Tools Required: Socket set, wrench set, torque wrench.
Remove the sway bar link from both ends by unbolting it from the sway bar and the control arm.
Replace with new sway bar links and bushings, ensuring they are tightened to manufacturer specifications.

4. Reassemble and Recheck

Reinstall the wheel and lower the vehicle.
Tighten lug nuts to the specified torque.
Reconnect the battery and ensure everything is properly secured.
