The Differential is one of the main components of the GMC Envoy vehicle train; one of its functions is to distribute the power generated by the engine to the drive wheels. This mechanism ensures that the wheels turn at different speeds a very vital aspect when cornering or maneuvering the car on rough terrains. Most of the GMC Envoy use open differentials designs that distribute equal amount of torque between the two wheels and LSD that distributes torque depending on the levels of traction. There are the open differentials which are quite easy to use but become a problem when the road conditions are bad as they cause spinning of one wheel. On the other hand, LSD enhances the car's performance through the ability to create disparate amounts of torque to the two wheels; the one with the better grip. Although both types offer some disadvantages, such as problems with handling at slippery surfaces, LSDs are guaranteed to give the rider more control and stability. Both types are required to be maintained and monitored frequently to avoid such problems as fluid leakage or component fatigue in order to have a properly working differential.
