What does a bad differential smell like?
A burning smell from your differential or gearbox is another sign you need near differential oil. The smell may be coming from oil leaking out of an old seal — you may even notice a reddish stain under your car’s parking spot. The burning smell might also be a result of an overheating gearbox from poor lubrication.
Do you need to break in new differential gears?
All new gear sets require a break-in period to prevent damage from overheating. Any overloading or over-heating will cause the gear oil to break down and cause undue stress to the ring & pinion gears.
What does burning differential fluid smell like?
Overheated or low transmission fluid could be a potential source of this burning smell. Fresh transmission fluid tends to smell sweet or tart. When that smell turns burnt, your transmission fluid has broken down and the system is burning too hot, leading to an increase in friction and corrosive activity in the engine.
When do you need to replace rear differential gears?
Replacing the rear differential gears. When teeth on the gears have chipped or worn badly, they must be replaced to eliminate the noise and potential for failure. These ‘hard parts’ are the costliest components, and repairs can only get one step worse.
Why is differential / gear oil so often forgotten?
Differential/gear oil is just one of the many important lubrication fluids that vehicles use in their normal operation. However, it is often one of the most forgotten fluids because it is not serviced nearly as frequently as others.
Why do I have a burning smell from my differential?
Burning Smell from Gearbox or Differential A burning smell from your differential or gearbox is another sign you need near differential oil. The smell may be coming from oil leaking out of an old seal — you may even notice a reddish stain under your car’s parking spot.

Why does the rear drive gear oil smell so bad?
Sulfur compounds are part of the extreme pressure lubrication additive pack needed by hypoid gears. Hypoid gears are found in rear-drive differential ring-and-pinion sets where the centerline of the pinion is offset below the centerline of the ring gear- it allows for the driveshaft to be lower and the floor of the car to be flatter.
