Disconnect the vehicle’s battery to avoid any electrical issues.

2. Inspect and Replace Components

Brake System

Sub-steps:
1. Remove the front wheel using a socket set.
2. Inspect the brake pads and rotors for wear; replace if necessary.
3. Tighten any loose caliper bolts and ensure proper installation.
4. Reinstall the wheel and torque to manufacturer specifications (typically 100 Nm).

Suspension System

Sub-steps:
1. Inspect struts, shocks, and bushings for signs of wear or damage.
2. Replace any worn suspension components as needed.
3. Reassemble and ensure all bolts are torqued to specifications.
