Uzgodnienie, że te Role of a Transferr Case in a Jeep

Te transfer case sites between thee transmissoon and thee front and rear axles, acting as central distribution hub for torque. When you shift into four- wheel drive, the transfer case locks power to both axles, giving you distribution one loose, slipery, or uneven surfaces. Withound a contrily functiving transfer case, your Jeep cannot deliver power where it ineeded coste.
