What is the difference between gear oil and differential oil?

Bend your finger downward slightly to see if it comes into contact with gear oil. If your finger touches gear oil, there is enough fluid inside.
How important is front and rear differential service?
Is differential service necessary? Yes! The differential uses oil, thicker than the oil that goes in the engine. Changing the oil in the differential is as important as the engine oil change because over time, the oil wears thin and becomes contaminated.

How do you fix a noisy differential?
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.
What does a rear differential problem sound like?
Clunking, rumble, or howl when cornering: This may indicate a problem with the spider, or side gear. Depending on how extreme the sound, it could mean there has been a leak of lubricant, a worn spider gear, or even a broken gear.
