13. INSPECT BRAKE LINE PIPES AND HOSESHINT: Check in a well lighted area. Check the entire circum-
ference and length of the brake hoses using a mirror as re-
quired. Turn the front whe els fully right or left before checking
the front brake.

DESCRIPTION
(SC400)
PR02N±04
The propeller shaft is a 2±part type, each part consisting of a strong, \
compact precisely balanced tube. The
propeller shaft is connected to the transmission and the differential via 3 joints. No.1 and No.3 joints are
made of flexible rubber couplings. No.2 joint is a Hooke's universal joint. All 3 joints are carefully arranged
in such a way that their shaft angles rest on a straight line. This design\
ensures a precise drive line linearity
from the engine through the differential to minimize noise and vibration.
A shaft length adjusting mechanism is incorporated in order to make prope\
ller shaft removal and reinstalla-
tion easier.

If using a new propeller shaft w / Phasemarks:
Install the propeller shaft phasemarks and differential phase-
marks so that their respective alignment phasemarks match.
If the propeller shaft phasemarks and differential phase-
marks do not align, install the propeller shaft and differential
alignment phasemarks are as close together as possible.
w / o Phasemarks:
Install the propeller shaft.
