Is the struts part of the drivetrain?

No, struts are not part of the drivetrain; they are components of a vehicle's suspension system. Struts help support the weight of the vehicle, absorb shocks from the road, and maintain proper wheel alignment. The drivetrain, on the other hand, includes parts such as the transmission, driveshaft, and axles, which are responsible for transferring power from the engine to the wheels.
