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).
