FAQ
Drivetrain - Common Questions
What is the difference between FWD, RWD, AWD, and 4WD?
FWD sends power to the front wheels and RWD to the rear. AWD powers all four wheels continuously with variable torque for on-road grip, while 4WD uses a transfer case with a low range designed for off-road and heavy towing.
What is a drivetrain?
A drivetrain is the set of components that delivers engine power to the wheels. It includes the transmission, driveshaft, differential, and axles, and in 4WD vehicles also the transfer case. The powertrain adds the engine itself.
What causes a drivetrain malfunction warning?
Drivetrain malfunction warnings usually point to sensor faults, transmission issues, transfer case problems, or faulty control modules. Reading the stored OBD-II codes with a vehicle-specific scan tool is the first step to pinpoint the cause.
