What causes drivetrain vibration?

Vibration in a driveshaft can be caused by many conditions.

What is included in a drivetrain warranty?

A drivetrain warranty includes the transmission, driveshaft, axles, and wheels, but it does not include the engine. A powertrain warranty covers everything that makes a vehicle move, from the engine to the transmission to the parts that allow power to travel from the engine to the wheels.

Does drivetrain include engine?

The drivetrain of a motor vehicle is the group of components that deliver power to the driving wheels. This excludes the engine or motor that generates the power. In contrast, the powertrain is considered to include both the engine or motor and the drivetrain.
