The open rear differential converts the 'angle of drive' through 90° and distributes drive, via the rear drive halfshafts, to the rear wheels.
The open rear differential for the V6 and V8 petrol variants has the same output ratio, but the output ratios for the TdV6 diesel are different, depending on whether automatic or manual transmission is fitted.
The open rear differential is located centrally in the rear of the chassis.
The units are mounted to the chassis via rubber bushes and bolts; two mounting points at the rear of the unit and one at the front.
