4MATIC front axle transmission, general 

The front axle transmission consists of a single-speed differential with fuel economy technology.

The housing of the front axle transmission is made of aluminum and is bolted to the engine oil pan via a carrier (7).

The drive pinion (2) is positioned at an 83° angle relative to the ring gear (3) to compensate for the angled path of the propeller shaft to the front axle transmission.

The ring gear (3) is attached at the engine end and bolted to the cage of the differential (4).

This positioning of the components of the front axle transmission reverses the change in rotation direction produced by the single-speed side output in the transfer case.
