Key Features

  • Wheel Rotation: Allows wheels to rotate at different speeds during turns to prevent wheel slips.
  • Power Distribution: This is the part responsible for applying torque to your vehicles that allows them to spin.

OEM MPN's: 1332803, 1332438, 1332831

Types of Differentials

  • Limited slip differential (LSD): Two output shafts to rotate at different speeds.
  • Torque vectoring differential: Uses electronic sensors to independently apply varying torque to each wheel.
  • Open Differential: Most common. differential Allows wheels to receive different amounts of torque while cornering. Bad for slippery roads.

When to replace?

  • Rumbling during turns.
  • Whirring during acceleration.
  • Whirring noise when decelerating.
  • Sustained clunking during movement.
  • Increasing Vibration as Vehicle picks up Speed.

NICHE Differential

  • The differential works to apply torque to both front and rear wheels.
  • A center differential can often be found in Four Wheel Drive vehicles.
  • This device is made up of a smaller set of both pinion and side gears that create the spider gear. This drives the rotational force of the case.
  • The drive axles are splined into the gears as the case spins, causing the wheels to turn.

Broke within 5 min of install on stock machine. Ring gear and pinion spacing must be out because they don’t engage properly
