What causes a noisy diff?
A clunking or banging when cornering, reversing, or quickly slowing down from highway speeds may be from worn spider gears or clutches, or lack of or incorrect lubrication. Hearing the noise when accelerating may be due to worn or loose axle or yoke splines, spider or U-joint wear, or differential backlash noise.
What does a noisy diff sound like?
Hearing an increase in the level of humming noises or gear grinding is a way of knowing almost for sure that you have a worn out differential. Usually the humming gets louder under acceleration. When this occurs it’s best to check the condition of your differential and replace if it’s in a rough condition.
How can you tell the difference between a bad and bad wheel bearing?
Unlike a wheel bearing, where the noise will change with wheel speed but typically will not change with variations in load (acceleration/deceleration), the noise heard from a failing bearing within the differential will make a roaring or growling noise on changes in load as well as changes in speed.
Do rear differentials make noise?
Gear whine, bearing noise and clunking are common rear differential noises that should be a concern to vehicle owners.
What makes a rear end Roar?
A noise that is heard when the vehicle is taking a turn is usually due to trouble in the axle shaft or a problem inside the differential itself. A bad axle bearing is usually the main reason for noise when cornering.
How often should I change diff fluid?
every 30k to 60k miles driven
Usually, differential fluid is changed after every 30k to 60k miles driven. This is a tough job, so must be handled by an expert technician. Only an experienced mechanic can properly wipe out the old different fluid from your vehicle’s drive-train.
What causes rear differential whine?
A whine during deceleration may mean there is a bad or loose pinion bearing. A howl during acceleration may indicate the same problem. Rumble or whining sounds only at speeds greater than 20 mph could be a sign of a worn carrier bearing. The sound may change while cornering.
