What causes a whirring noise from the rear axle?
Here are a few common “noises” that may come from the rear axle that need immediate attention: • A “whirring” noise while decelerating at any or all speeds is most likely caused by bad pinion bearings or loose pinion bearing preload.
Why does rear differential noise sound like a broken gear?
Having a chipped or missing high spot on a gear tooth sounds closely similar to a broken gear except that the rear differential noise only happens while accelerating or decelerating. This is because the problem is just present on one side of the offending tooth.
What causes a whine in the rear end of a car?
The pinion gear is turned by engine force and subject to bearing wear from the forces applied. Quiet gear action is directly related to proper matching of gear surfaces. Maladjusted or worn gears create whine at different speeds or loads. The whine will be constantly present, but may change pitch or intensity.
What causes a whining noise in the differential?
Whining Noise on Acceleration/Deceleration. A whining or howling differential noise on accelerating or decelerating may be caused by a loose gear inside the differential. Vibration. A worn U-joint can cause vibration through the vehicle, as can a driveshaft being out of balance.

What causes a howling noise in the rear of a car?
Cause:Worn rear pinion bearing or worn gear set Noise:Howl without whir or rumble while accelerating at any speed (gears previously quiet) Cause:Worn gear set due to lack of lubrication or overloading Noise:Howling while accelerating over a small speed range (gears previously quiet) Cause:Worn gear set due to lack of lubrication or overloading
Why are my gears making a loud noise?
In this case, the gears typically aren’t the problem at all. Instead, it’s often a loose pinion yoke, bad U-joint, or worn transmission making the noise. Possible Cause #2: A second possible cause is the crush sleeve. If the crush sleeve is not crushed properly, the pinion yoke will be loose and the pinion bearings will not be seated correctly.

What kind of noise does rear differential make?
Gear whine, bearing noise and clunking are common rear differential noises that should be a concern to vehicle owners. There are various situations which can create rear differential noise. For example, howling of gears is a sure sign of wearing.
Why is my axle bearing making a growling noise?
It may also eliminate other items that can be mistaken for axle shaft bearing noise. Bad axle bearings often make a growling or rumbling sound at highway speeds. Changing lanes may cause the noisy bearing to either increase or decrease the noise level.

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.
What’s the difference between wheel bearing noise and rear differential noise?
Thankfully there are a few simple things that can help distinguish between rear differential noise and wheel bearing noise. Wheel Bearing Noise. Simplest check to identify a failing wheel bearing is to suspend the car so that the wheel does not touch the ground. Then grab the wheel and wiggle it back & forth.
What does it mean when your differential is making a noise?
While there is no help for our singing, we can help you diagnose the sounds coming from a differential gone bad. A clunk, whine, or howl can signal a worn-out pinion gear, bad bearings, or a faulty gear installation. Sometimes, the noise is not differential-related, but is caused by other driveline or axle components.
What causes a clunking noise on the driveline?
Cause: Bad wheel bearings Noise: Driveline squeaking or grinding at any speed Cause:Worn or damaged U-joints Noise: Clunking when depressing the throttle pedal (takeoff) Cause:Worn U-joints; worn spider gears; worn axle splines; excessive gear backlash; loose yoke splines; worn slip yoke splines Noise:Clunk immediately after taking off from a stop
Why does my rear differential make so much noise?
You want to listen to the noise. If it gets louder when steering left, it’s the left wheel bearing, louder to the right is the right wheel bearing. However, if the noise stays the same, it’s rear or front differential noise.
Why does my front wheel make a grinding noise when I drive?
Wheel bearings are what allow your tires to spin freely and smoothly while the vehicle is in motion. If the bearings begin to seize up or they get dirty and that prevents them from doing their job properly then you’re going to be experiencing grinding and knocking sounds while you’re driving.
Why do I hear a knocking noise from my front wheel?
Bushings are typically just made of rubber so they will wear down over a long enough timeline, especially if they’re under a lot of stress. When your bushings wear down far enough or they actually break you’re going to hear a knocking sound caused by metal parts hitting against one another without the bushings there to buffer them any longer.
