If the preload is greater than the specification, replace the
spacer.
If the preload is less than the specification, retighten the nut with
a force of 13 N·m (130 kgf·cm, 9 ft·lbf) at a time until the speci-
fied preload is reached.

Torque: 490 N·m (5,000 kgf·cm, 362 ft·lbf) or less

If the maximum torque is exceeded while retightening the nut,
replace the spacer and repeat the preload procedure.
Do not back off the nut to reduce the preload.

REMOVE DIFFERENTIAL MOUNTING CUSHION

Using SST, remove the differential mounting cushion.

SST

09316–12010, 09570–24010

NOTICE:

When driving out the mounting cushion, be careful
not to touch the suspension member with the SST.

Align the SST straight so that the bolt of the SST is
parallel with the center line of the mounting cushion.

When installing the bolts to the LH and RH differential
mounting cushions, make sure that the bolts are
passed through the correct holes in the SST, as
shown in the illustration.

3.

INSTALL DIFFERENTIAL MOUNTING CUSHION

Using SST, install the cushion so that the marks are positioned,
as shown in the illustration.

SST

09570–24010

NOTICE:

Pay enough attention to LH and RH sides or top and
bottom.

Set the SST after temporarily installing the differential
mounting cushion into the member so as not to install
at an angle.

To confirm that the differential mounting cushion is
aligned straight in relation to the member, check that
the SST is fully in contact with all of the cushion.
