Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the battery to avoid electrical issues during repairs.
Raise the vehicle using a hydraulic jack and secure it with jack stands.

2. Inspect and Replace Worn Components

Control Arms
- Remove the wheels for better access.
- Inspect control arm bushings for cracks or excessive play.
- If necessary, remove the bolts securing the control arms and replace them with new ones.
- Torque specifications: 85 Nm (62 lb-ft) for the control arm bolts.
Struts/Shocks
- Inspect struts and shocks for signs of fluid leakage or damage.
- Remove the strut assembly by unbolting it from the top mount and lower control arm.
- Replace struts or shocks if damaged. Follow manufacturer guidelines for installation.
- Torque specifications for top mount bolts: 30 Nm (22 lb-ft).
Sway Bar Links
- Check sway bar links for wear or looseness.
- Remove and replace any damaged links, ensuring to torque the bolts to 40 Nm (30 lb-ft).

3. Reassemble and Lower Vehicle

After replacing components, reassemble the suspension.
Ensure all bolts are tightened to factory specifications.
Reinstall the wheels and lower the vehicle back to the ground.

4. Final Inspection

Double-check all connections and component integrity.
Conduct a visual inspection to ensure no tools are left in the engine bay or under the vehicle.
