1. REMOVE DIFFERENTIAL(See page SA±82)
2. REMOVE DIFFERENTIAL MOUNT CUSHION Using SST, remove the differential mount cushion.
SST 09316±12010, 09570±24010
NOTICE:
w When driving out the mount cushion, be careful not to
touch the member with the SST.
w Align the SST straight so that the bolt of the SST parallels
the center line of the mount cushion.
w When installing the bolts to the LH and RH differential
mount cushions, make sure the bolts are passed through
the correct holes in the SST, as shown in the illustration.
3. INSTALL DIFFERENTIAL MOUNT CUSHION Using SST, install the cushion so that the marks are posi-
tioned, as shown in the illustration.
SST 09570±24010
NOTICE:
wDo not make a mistake with left and right sides or top
and bottom.
w Set the SST after temporarily installing the differential
mount cushion into the member so as not to be installed
at an angle.
w To confirm that the differential mount cushion is aligned
straight in relation to the member, check that the SST is
fully in contact with all of the cushion.
