GENERAL PROCEDURES
PowertrainIDrivetrain Mount Neutralizing(l4 001 0)
N0TE:There is no procedure for neutralizing the
powertrainldrivetrain mounts. To check the
alignment of the powertrain mounts visually,
proceed as follows.
I. Loosen the rear support insulator retaining
bolts (if equipped).
2. Loosen the powertrainldrivetrain mount
retaining bolts.
3. N0TE:Support the powertrainldrivetrain in
an approximate position and height.
N0TE:Make sure that the right-hand mount and
left-hand insulator align over the studs on the
powertrain and drivetrain to allow the fixings to be
assembled through the large holes in the support
insulator bracket without overstraining.
Check the powertrainldrivetrain mount
alignment.
4. Tighten the powertrainldrivetrain mount to
powertrainldrivetrain mount bracket retaining
bolts.
5. Tighten the powertrainldrivetrain mount to
body retaining bolts.
6. Tighten the rear support insulator retaining
bolts (if equipped).

DESCRIPTION
AND OPERATION
Item Description
The rear rubber mountings for the lower
suspension arms are enclosed in aluminium
brackets. This provides more vibration damping
than previously. Both the front and rear brackets
are arranged horizontally.
1
The suspension strut turret support bearings have
two separate routes for independently deflecting
the spring and shock absorber forces into the body.
This reduces the level of noise transmitted from
the road surface. Rear rubber
mounting
The correct installation position must be observed
when installing the suspension strut turret support
bearings. This is indicated by an arrow on the
suspension strut turret support bearing. The shock
absorbers are gas shock absorbers.
The spring travel has been increased by
6 mm,
and the track has been increased by
48 mm to
1477 mm.
