Recently we got a member asking if a 4Matic Mercedes-Benz can be converted to a rear wheel drive.
First, why would anyone want to do this?
The reason is often because a Mercedes-Benz owner has bad CV joints or bad differential on the front. Because those repairs can range from $1500-$5000, it makes one wonder if you can convert an all-wheel-drive Mercedes-Benz into a rear wheel drive.
Converting a Mercedes-Benz from 4Matic to RWD is not as simple as removing the front propeller shaft. Doing just this is not enough. Puting your Mercedes-Benz in drive, will send all the torque to the removed propeller shaft. The output flange at the transfer case will spin constantly and the vehicle will not move.
To convert a Mercedes 4Matic to a rear drive not only do you need to remove the front propeller shaft from the transfer case to the front differential. To convert a 4Matic to RWD you will need to remove the transfer case as well. Next connect the output shaft from the transmission directly to the rear differential.
