What aspect of the towed vehicle's drivetrain do engineers aim to eliminate?

Engineers focus on eliminating the need for lubrication in the towed vehicle's drivetrain to ensure greater reliability and lower maintenance concerns for towing applications. In many circumstances, especially in off-road or heavy-duty towing scenarios typical of Jeep applications, a simpler drivetrain that doesn’t require regular lubrication can lead to enhanced durability and reduce the risk of failure during operation. By minimizing the necessity for lubrication, engineers can also decrease the complexity of the vehicle systems, resulting in lighter weights and improved performance on rugged terrain where Jeeps often operate.

Eliminating the need for lubrication can significantly simplify the design and maintenance of the drivetrain components. Unlike oil changes or standard lubrication methods that require routine checks and services, a design that does not depend on lubrication can help keep the towed vehicle in service longer and require less attention from the operator.
