Gear Noise

WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.

Gear noise or whine is audible from 32 - 89 km/h (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 48 - 64 km/h (30 - 40 mph) and 80 - 85 km/h (50 - 53 mph). Gear whine is corrected by ring and pinion gear replacement or adjustment, depending on the mileage of the gear set.
