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 GUIDELINES FOR CLEAN WORKING CONDITIONS .
• All chassis component bolts with bonded rubber bushings must be tightened in the control position.
• Bonded rubber bushings have a limited range of rotation. Before axle components with bonded rubber bushings are tightened, they have to be brought to a position which matches the position when the vehicle is being operated (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 WHEEL BEARING IN CURB WEIGHT POSITION, LIFTING VEHICLES WITH COIL SPRINGWHEEL BEARING IN CURB WEIGHT POSITION, LIFTING VEHICLES WITH COIL SPRING or determine the standard vehicle height (refer to WHEEL BEARING AT STANDARD VEHICLE HEIGHT, LIFTING VEHICLES WITH AIR SUSPENSION ).

-- Move the wheels so that they are straight.

-- Switch off the ignition.
