CAUTIW: Under no circumstances must the flexible
coupling (or itsfixings) be loosened or removed
from the drive shaft flange.
. Remove fixings center bearing to crossmember (1 Fig. 1) and push drive shaft rear section forward to disengage
from pinion spigot. Fig. 1
w: Take account of any shims located between the center bearing and the crossmember.
. Release fixings and remove, over axle exhaust pipe mounting from wide mounting bracket.
. Support the rear suspension assembly from below and remove fixings from RH and LH sides in the following order:
1. Shock absorber to body upper fixings.
2. Differential strut to body (1 Fig. 2).
