Gear Noise

Gear noise or whine is audible from 20-55 MPH under 4 driving conditions:

• Drive - Acceleration or heavy pull.
• Road Load - vehicle driving load or constant speed.
• Float - Using enough throttle to keep the vehicle from driving the engine, the vehicle slows down gradually but the engine still pulls slightly.
• Coast - Throttle is closed and the vehicle is in gear.

Gear noise most frequently has periods where the noise is more prominent, usually between 30-40 MPH and 50-53 MPH. Gear whine is corrected by either ring and pinion gear replacement or adjustment, depending on the mileage of the gearset.
