Why does my ring and pinion make a noise?
This kind of noise is almost never caused by bad ring and pinion gears. A howl or whine during acceleration over a small or large speed range is usually caused by worn or burned ring and pinion gears or improper gear set up.
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.
How does a differential work on a pinion gear?
While differentials do not involve reciprocating masses, the built-in resistances in a properly set up differential maintain a situation in which one tooth on the pinion gear comes into contact with a tooth on the ring gear at the exact moment that a tooth on the pinion gear loses contact with a tooth on the ring gear.
What causes the pinion gear teeth to be sharp?
The face or edge of the pinion gear teeth is worn to the point of being sharp. Burning like this is caused by lubrication failure. There was not enough oil in the differential, or the differential was not properly set up, became too hot, and the oil broke down.

What causes a whirring noise in a differential?
Differential Problems. Whirring noise only while decelerating at any or all speeds is most likely caused by bad pinion bearings or loose pinion bearing preload. This kind of noise is almost never caused by bad ring and pinion gears.
This kind of noise is almost never caused by bad ring and pinion gears. A howl or whine during acceleration over a small or large speed range is usually caused by worn or burned ring and pinion gears or improper gear set up.
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.
How do you replace a rear differential pinion seal?
A rear differential pinion seal necessitates the removal of the yoke where the driveshaft and diff meet. Remove the seal around the yoke and replace it without damaging the new one. Reassemble and refill the differential oil. The side seals prevent the oil from seeping into the brakes.
