- Secure with jack stands and remove the wheel.
Examine Brake Pads and Rotors
- Inspect brake pads for thickness; replace if worn below manufacturer's specifications (typically less than 3mm).
- Check rotors for scoring or warping; machine or replace if needed.
- Clean the brake components with brake cleaner to remove dust and debris.
Reassemble
- Reattach the wheel and lower the vehicle.
- Torque lug nuts to manufacturer specifications (typically around 80-100 lb-ft).

3. Inspect and Replace Accessory Drive Belt

Remove Engine Cover (if applicable)
- Unscrew and lift off the engine cover to access the belt area.
Check Belt Condition
- Inspect the belt for cracks, fraying, or glazing. Replace if any damage is found.
Replace Belt
- Loosen the tensioner using a wrench or ratchet.
- Remove the old belt and install the new one following the routing diagram usually found on the engine bay.
- Ensure the belt is properly tensioned.

4. Test Drive

After repairs, conduct a test drive to confirm the squealing noise has been resolved.
