Solution

1. Preparation

Gather tools and parts needed for repair.
Park the vehicle on a flat surface and engage the parking brake.
Gather safety equipment (gloves, goggles).

2. Inspect and Replace Worn Components

Bushings:
- Remove the affected suspension component (e.g., control arms).
- Use a socket set to remove bolts and nuts.
- Replace worn bushings with new ones, applying a suitable lubricant.
Shocks/Struts:
- Remove the shock or strut assembly by loosening the bolts at the top and bottom.
- Replace with new shocks/struts as necessary.
- Torque bolts to manufacturer specifications (refer to service manual for specific torque values).

3. Check and Tighten Loose Parts

Inspect all mounting bolts and fasteners for tightness on suspension components.
Tighten any loose bolts to manufacturer specifications.

4. Lubricate Components

Apply silicone-based lubricant to sway bar bushings and links to reduce friction and noise.
Check for proper lubrication of ball joints and reapply if necessary.
