A transfer case in a vehicle is an important part as it is responsible for receiving power from the transmission and sending it to both the front and rear axles to in turn supply power to all four wheels. It is impossible to drive a car without a transfer case as this means that the power can’t be split properly between the front and rear driveshafts. However, to maintain the transfer case in good condition, the transfer case fluid should be changed every 30,000 miles especially in vehicles that use a four-wheel-drive a lot. Failure to do so might lead to the transfer case fluid becoming sullied or running low which can prompt the transfer case to burn up.
If you notice that your transfer case is not in good condition, make sure to repair it or replace it quickly. It is never a good idea to drive a car with a bad transfer case. Driving a car with a bad transfer case can mean damaging the car beyond repair by causing damage to the transfer case, driveshafts, and axles.
