Question

1. a vehicles right front wheel has a growling noise that increases with vehicle speed. the most likely cause is: excessive rotor lateral run out. warped rear brake drums. a worn cv - joint. a worn wheel bearing.

Explanation:

A worn wheel - bearing often produces a growling noise that increases with vehicle speed. Excessive rotor lateral run - out usually causes brake pulsation or vibration. Warped rear brake drums affect rear - braking performance, not front - wheel noise. A worn CV - joint typically makes clicking or popping sounds during turns, not a growling noise that increases with speed.

Answer:

A worn wheel bearing.
