Procedure

With the lock carrier installed, the engine is removed downward with the transmission and subframe.
Install cable ties at the same locations when installing.
Pay attention to the guidelines for clean working conditions. Refer to appropriate Service Information .
All chassis component bolts with bonded rubber bushings on vehicles with coil spring in the curb weight position (unloaded condition) or on vehicles with air suspension must be tightened in control position.
Bonded rubber bushings have a limited range of rotation. Axle components with bonded rubber bushings must be brought into the position they will be in when driving before they are tightened (curb weight position or control position). Otherwise, the bonded rubber bushing will be under stress, which will reduce the service life.

-- Before starting the procedures, determine the curb weight position (refer to appropriate Service Information or determine the control position (refer to appropriate Service Information ).

-- Move the wheels so that they are straight.

-- Switch off the ignition.

The electro-mechanical parking brake must be released before disconnecting battery so the driveshaft can be rotated to remove it.

-- De-energize the 48 Volt system and disconnect the battery. Refer to BATTERY A, DISCONNECTING AND CONNECTING, VEHICLES WITH HIGH-VOLTAGE SYSTEM, (0K3) .

-- LHD: Remove the right cover -1- toward the rear in direction of -arrows- and remove.
