Struts/Shocks:
1. Remove the wheel to access the strut assembly.
2. Disconnect the strut from the upper mount and lower control arm.
3. Replace the strut or shock absorber if damaged.
4. Reinstall the new strut and torque bolts to manufacturer specifications.
Control Arms/Bushings:
1. If the control arms are worn, remove the bolts securing them to the chassis and the knuckle.
2. Replace with new control arms or bushings as necessary.
3. Torque new bolts to manufacturer specifications.
Sway Bar Links:
1. Remove the sway bar link from the sway bar and lower control arm.
2. Install new sway bar links and torque to the recommended settings.

4. Reassemble and Lower the Vehicle

Reinstall the wheel and tighten lug nuts in a star pattern to the specified torque.
Lower the vehicle from the jack stands using the hydraulic jack.

5. Final Inspection

Recheck all bolts and connections to ensure they are secure.
Inspect the area for any leftover tools or parts.
