Step-by-Step DIY Diagnostic Checklist
Perform these physical checks safely before visiting an auto shop to isolate whether the issue is simple external hardware or internal mechanical wear:
- ✓Visually inspect brake rotor friction rings through wheel spokes for deep gouges or metal scoring.
- ✓Jack up suspected wheel and safely check for 12-to-6 o'clock wobble or roughness when spinning.
- ✓Observe whether grinding noise changes pitch when vehicle weight shifts during left/right sweeping turns.
