When to listen for a rear differential noise?

But you can’t lay underneath your vehicle and see where the noise is coming from because you can only hear it when the vehicle is moving! That’s why when you’re diagnosing a rear differential noise, you should have at least two people in the car to listen from where it is coming.

When do you know something is wrong with your rear differential?

The first sign that there’s something wrong with your rear differential will be something that you hear. But, people often misdiagnose rear differential noises, leading to a panic-inducing headache until the repair shop tells you what’s really going on.

What causes a howling sound in the rear differential?

Broken teeth on the axle gear can result in complete loss of power when turning in any direction and eventually reaching a point where the gears don’t engage at all anymore, bringing the car to a complete standstill. There are various situations which can create rear differential noise. For example, howling of gears is a sure sign of wearing.

Why does my rear differential make a clunking noise?

If the pinion bearings are the problem, they create more of a whirring noise than a rumble because it turns several times faster than the carrier assembly. Regular clunking every few feet can also be an indicator of a broken pinion gear and/or chipped and damaged ring gear.

If the pinion bearings are the problem, they create more of a whirring noise than a rumble because it turns several times faster than the carrier assembly. Regular clunking every few feet can also be an indicator of a broken pinion gear and/or chipped and damaged ring gear.

Why is differential noise most common on acceleration?

People talk about differential noise on acceleration because it’s the most common area where noise occurs from on acceleration. Reason is that the load on the gears makes it harder for the teeth to slide across each. This also increases load on the carrier bearings making them prone to failure also (and they too get really noisy).

Broken teeth on the axle gear can result in complete loss of power when turning in any direction and eventually reaching a point where the gears don’t engage at all anymore, bringing the car to a complete standstill. There are various situations which can create rear differential noise. For example, howling of gears is a sure sign of wearing.

What causes a low pitch noise when accelerating?

Noise:Howling while accelerating over a small speed range (gears previously quiet) Cause:Worn gear set due to lack of lubrication or overloading Noise:Howling after gear set installation Cause:Faulty gears or improper installation Noise:Low-pitch rumble at all speeds over 20 miles per hour Cause:Worn carrier bearings
