Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure with wheel chocks.
Raise the vehicle using a jack and support it on jack stands.

2. Inspect and Replace Suspension Components

Inspect shocks and struts:
- Remove the wheel to access the shock/strut assembly.
- Check for leaks, dents, or physical damage.
- If damaged, proceed to replace with new shocks/struts.
Replace worn bushings:
- Identify any worn or cracked bushings in the control arms or sway bar.
- Remove the bolts securing the control arm or sway bar.
- Replace old bushings with new ones and reassemble using specified torque values.

3. Check and Tighten Mounting Points

Inspect and tighten hardware:
- Examine all bolts and nuts on suspension components.
- Tighten any loose hardware to manufacturer specifications.
Replace any damaged mounting brackets:
- If any brackets are bent or broken, replace them to ensure proper suspension alignment.

4. Reassemble and Lower Vehicle

Reinstall the wheel and lower the vehicle from jack stands.
Perform a final check to ensure all components are secure and no tools are left under the vehicle.
