The first sketch of an AWD system was in 1903 by Gottlieb Daimler, the son of Paul. The Mercedes 4 wheel drive and AWD system has gone through a series of developments. Mercedes introduced a 4Matic with ESD (Electronic Lockable Differential) was in 1987/1988 in the E-Series. Then in 1997 the first 4-ETS (Electronic Traction System) coupled with the 4Matic was released in the M-Class SUV. In 2009 a new light weight under 200 pounds 4Matic system with some added enhancements was put into production. The 4Matic balances the power, control and torque with the 4-ETS (Electronic Traction System) which provides gripping power by using the already existing sensors of the ABS (Anti-locking Braking System) and the ESP (Electronic Stability Program) systems. Mercedes is known for its innovation and achievements in the development of the auto.
The transmission sends the power to the transfer case and from there it is sent to the rear and front axles. There are two types of transfer case housings. There is the transfer case that is divorced or independent from the transmission and is down lower from the drive train mostly on longer vehicles. There is also the married transfer cases that are directly bolted to the transmission and sometimes they share the housing.
The fluids in the transfer case are there to protect the interior gears and to keep the parts clean. It also lubricates the moving parts (bearings, gears, shafts, chains, and other parts) and cools the transfer case while the parts are engaged. While some transfer cases take traditional gear oil, others use synthetic oil, or transmission fluids, and others take special fluids. Over time the fluids become polluted and the lubricating, cleansing and heat reducing properties are degraded and can shorten the life of your transfer case working parts.
The transfer case is part of the vehicle’s drivetrain, and engages the 4-wheel drive or AWD systems. Some part time 4WD systems operate in a two wheel mode unless a lever, button or some engage automatically. These vehicles are typically driven in 4WD over difficult terrain then switch back to 2WD on the highway. Typically, the transfer case allocates the power from the driveshaft linking the axles and all 4 wheels to receive simultaneous torque. The 4-wheel drive system locks the front axle driveshaft to the rear axle driveshaft and forces the wheels to all turn at the same speed.
With the advent of the full time AWD system with three differentials, there is a center differential, plus a differential in the front and a third in the back. The wheels can now move independently with the AWD system moving the vehicle over highway and smooth handling through inclement weather conditions. This new break-away clutch in the center differential allows the wheels to move independently at different speeds. The new 4-wheel traction control is an electronic control that applies the ABS brakes to the wheel spinning and applies the power to the other wheels that have traction. This keeps the vehicle under better control.
The newer Mercedes vehicles from 2007 have an AWD system that is attached and geared with the backend of the automatic transmission and appears to be fully integrated appearing as nearly one unit with the transmission. This type only comes only with an automatic transmission, because of the way they are attached and geared jointly.
The Mercedes from 2006 and older did have a separate transfer case on some of its models just behind the transmission and in front of the power shaft. It is recommended to change the transfer case fluids about every 100K miles depending on the model, some prefer every 50K miles because they tend to get dry or the fluid tends to become more thickened. Some of the vehicles have both a drain and fill plug located under a small plate near the front center of the vehicle on the underside, while some models only have a single plug. With the single plug a hand pump or vacuum bleeder can be used to drain the nearly .5 liter of fluid at a time before refilling. To clean it thoroughly additional fluids may be needed to refill and drain at least two to three times if it is very dirty. With a double plug it’s a much easier process where the fluid can be drained nearly completely and refilled with proper OEM recommended fluid.
