5) Remove spring pins from DOJ and BJ with a 6 mm
(0.24 in) diameter of steel rod. Next, lower trailing arm ASSY
all the way; remove BJ from spindle on the trailing arm side
first, then DOJ on the differential side. Remove drive shaft
ASSY.
6) Remove propeller shaft ASSY.
a. Prepare an oil can and cap since the transmission oil flows
out from the extension at removing propeller shaft ASSV.
b. When removing propeller shaft ASSV, pay attention not to
damage the sliding surfaces of rear drive shaft (extension)
spline, oil seal and sleeve yoke.
c. Insert the cap into the extension to prevent transmission oil
from flowing out immediately after removing the propeller
shaft ASSV.
