1. Remove the rear propeller shaft. Refer to PR-8, "REMOVAL" .
2. Put a matching mark on the end of the drive pinion correspond-
ing to the C position matching mark on the final drive companion
flange.
CAUTION:

For matching mark, use paint. Never damage drive pin-
ion.

The matching mark C on the final drive companion flange
indicates the maximum vertical runout position.

gear has engaged the serrated part of flange, remove the pro-
tector.
c. Put suitable drift on the center of side flange, then drive it until
sound changes.
NOTE:
When installation is completed, driving sound of the side flange
turns into a sound which seems to affect the whole final drive.
4. Confirm that the dimension of the side flange installation (Mea-
surement A) in the illustration comes into the following.
5. Install the drive shaft and axle assembly. Refer to RAX-9,
