Wheel bearing diagnosis: 1) Noise changes when changing lanes or sweeping = bearing on side with more weight (turning left, load shifts right, if noise gets louder = right bearing bad). 2) Jack up suspect corner, spin wheel by hand — roughness or grinding = bad bearing. 3) Check for play — grab wheel at 12 and 6, rock it — any play = bad bearing. Replace as complete hub assembly on most modern cars. Driving on bad bearing risks wheel separation — do not delay.
Wheel bearing noise — grinding or humming while driving

Common causes include sensor failures, wiring faults, and component wear. Always read additional fault codes before replacing parts — multiple codes together provide a clearer diagnosis.
