What does it mean when your differential is leaking?
Differential oil leaks If the seals dry or wear out, they will leak fluid from the axle shafts. Smaller leaks may produce faint traces of gear oil coming from the differential housing while larger leaks will produce drips and puddles underneath the vehicle.
What happens if you don’t change your differential fluid?
Most differentials need a fluid change at about 50,000 miles. If left too long or if the fluid starts to run low, the differential will become noisy and can eventually fail. If that happens, the gears can seize, locking up the rear wheels and potentially causing a lot of damage or even an accident.
What happens when automatic transmission fluid is low?
Overheated transmission: If you experience a loss of power, smoke coming from your car, a burning smell, or erratic shifts you need to pull over immediately. Delayed gear engagement: When you’re low on transmission fluid you will experience a noticeable pause (2 to 3 seconds) when you shift into Drive and Reverse.
