Gear Whine
Gear whine is a high-pitched noise from a gearbox or differential that changes with speed or load.
What is Gear Whine?
It can occur in only one gear. Worn bearings sound similar. Low oil makes it worse. Noise under load that disappears when coasting often comes from one gear set; noise that changes with speed in all gears often comes from bearings or the differential. A road test with a mechanic can locate it.
How it works
Worn or badly meshed gear teeth vibrate.
Why it matters for your car
Check the oil level first. Rising noise needs inspection.
