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.
Why does my rear differential make a whirling noise?
Rumbling and whirring noises at speed over 20 mph, moreover, can be the result of worn carrier bearings. For vehicles with C-clip axles, the rear differential noise may change at different turns.
Why is my rear differential Howling under acceleration?
Howling under acceleration at various speeds, however, indicates that the gears are already worn out or are out of alignment or depth with each other. If rear differential noise occurs while accelerating the car only at a certain speed, it is likely because the gears have become worn due to overloading and lubrication failure.
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

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.
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.
When does a manual transmission make a whining noise?
A manual transmission is only turning when the car is either in motion, or when the transmission is in Neutral and the clutch is engaged (your foot is off the pedal). So sounds that occur while the car is stationary and in gear are most likely associated with the clutch.
What to do if your car makes a whining noise when not in gear?
Step 1: Ruling out engine noise. If the car doesn’t make the noise when it is not in gear, chances are it isn’t an engine noise. Race the engine gently with the car in Neutral and listen carefully for any signs of the offensive noise that are associated with the engine speed.
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 does my car make a whining noise when in reverse?
When the car is is in reverse, the transmission pressure rises and the transmissions demand for fluid rises with it. A restricted filter will not allow the fluid to pass quickly enough. You can change the fluid and filter if this is the case or have it done for you but it might not be the end of your troubles.
