If the rear axle was delivering the same torque to both wheels, the left rear bike would be binding and skittering as information technology fabricated the plough. The differential is designed to allow the wheels to turn at different speeds around corners, eliminating that problem.

The differential uses an oil thicker than motor oil, somewhere between an oil and a grease in terms of its weight. Like any other assembly, though, the oil in the differential will become contaminated over fourth dimension and volition commencement to break downwardly due to heat. Most differentials need a fluid change at about fifty,000 miles. If left too long or if the fluid starts to run low, the differential will become noisy and can eventually neglect. If that happens, the gears tin seize, locking up the rear wheels and potentially causing a lot of damage or fifty-fifty an blow.

Differentials have a fill hole, sometimes covered with a rubber plug that makes it easy to check the oil level. They don't, however, have a drain plug, meaning that the only mode to modify the oil is to remove the differential'due south rear cover. This is inevitably a messy job that'southward all-time left to professionals. Remember also that on 4WD vehicles, there's a second differential for the front wheels. For 4WD vehicles, it's usually a adept idea to perform service on both differentials and the transfer instance at the same time.
