Check and Tighten Suspension Bolts:
- Using a torque wrench, check all suspension component bolts for proper torque specifications.
- Tighten any loose bolts to manufacturer specifications.
Replace Bushings (if necessary):
- Remove the control arm if bushings are worn.
- Use a bushing removal tool to replace the old bushings with new ones.
- Reinstall the control arm and torque the bolts to specifications.
Inspect and Secure Exhaust Components:
- Check exhaust hangers and brackets for wear or looseness.
- Tighten or replace any loose components to reduce rattling noise.
Reassemble and Lower Vehicle:
- Reinstall all removed components and ensure everything is tightened.
- Carefully lower the vehicle and remove the jack stands.
