up out of the way.

secure the hub carriers to the U-clamps at the
base of the suspension struts (photo).
23 Pull the tops of the hub carriers from the
clamps and release the driveshafts from the
hub carriers.
24 Tie the driveshafts in a horizontal plane
with lengths of wire.

trolley jack under the engine/transmission and
remove the bottom mounting and then the
upper left and right-hand ones (photo).
26 Carefully lower the power unit to the floor
and withdraw it from under the car.
27 External dirt and grease should now be
removed using paraffin and a stiff brush or a
water-soluble solvent.

brackets and the starter motor.

gearchange ball stud strut from the lower front
face of the flywheel housing.

connecting bolts noting the location of any
lifting lugs and hose and wiring brackets.
