Why does my rear differential make a whirring noise?
Hearing a whirring noise around 10 mph when accelerating or slowing down is likely due to worn or loose pinion bearings. Worn axle shaft splines or chipped gear teeth can lead to a knocking or clicking rear differential noise from the differential.
What does a worn pinion bearing sound like?
Generally, worn out pinion bearings can create whirring noises at various speeds, be it may during deceleration and/or acceleration. Overly worn out bearings tend to make a howling noise when they do not properly support the gears. Rumbling while turning, on the other hand, is a sign of bad wheel bearings.
What should I do if my differential is making noise?
How to fix a noisy differential: Replacing the differential fluid may stop the sound, or replacing a pinion or side seal may solve the problem. However, once the noise gets bad, rebuilding or replacing the differential may be the best way to fix the noise.
Why does my differential clunk when I accelerate?
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. The clunk, when starting from a stop, could be caused by worn out slip yoke splines.

What causes wheel bearings to make a noise?
▶ Do not confuse wheel bearing noise with that produced by a damaged CV joint; both the problems are different from each other and they need be dealt with separately. ▶ Noise produced by wheel bearings is a result of lack of lubrication and in some cases, physical damage caused to them.
What causes a whirring noise at all speeds?
Here are a few typical symptoms and their possible cause: Whirring noise only while decelerating at any or all speeds is most likely caused by bad pinion bearings or loose pinion bearing preload, and almost never by bad ring and pinion gears.
How to diagnose differential noise in a car?
Diagnosing Differential Noise. • “Rumbling or whirring” at speeds over 20 mph can be caused by worn carrier bearings. The noise may change while cornering or turning. • Regular “clunking” or loud “clicking” every few feet may indicate a broken ring or pinion gear tooth.
What does it mean when your rear end whines?
The sound level can bring minor annoyance, or foretell serious part failure. Timely reaction to a rear end whine may prevent the need for repair or replacement of expensive differential components. Understanding differential parts and maintenance may help determine the severity of the problem.

Why is my rear differential making a whiny noise?
Having posted on Benzworld several times about an annoying whining noise coming from the rear, I finally got up the courage and replaced the rear Differential. Originally, I discounted the differential as being the source of the noise because I had not read a single post here or on any of the other forums of anyone replacing a differential.

Why does my Mercedes Benz make a whiny noise in the rear?
(He has been on a mission!) It was now time to take the next step and change out the differential which is the most obvious culprit of the three moving components in the rear, ie, the differential and two axle shafts.
