Valve Body
Repair
NOTE: This repair is only necessary il one or more of
the valves in a valve body do not slide smoothly in their
bores. You may use this procedure to lree the valves in
the valve bodies.
1. Soak a sheet of #600 abrasive paper in ATF for
about 30 minutes.
2. Carefully tap the valve body so the sticking valve
drops out of its bore.
CAUTION: lt may be necessary to use a small
screwdiiver to pry the the valve lree. Be carelul not
to sclatch the bore with ihe sc.ewdliver.
3. Inspect the valve tor any scuff marks. Use the ATF-
soaked # 600 pagper to polish off any burrs that are
on the valve, than wash the valve in solvent and dry
it with compressed air.
4. Roll up halt a sheet oI ATF-soaked paper and insert
it in the valve bore of the sticking valve.
Twist the paper slightly, so that it unrolls and fits
the bore tightly, then polish the bore by twisting the
paper as you push it in and out.
CAUTION: The valve body is aluminum and doesn't
require much polishing to remove any burs.
W
5.
6.
7.
Remove the #600 paper and thoroughly wash the
entire valve body in solvent, then dry with com-
perssed air.
Coat the valve with ATF then drop it into its bore.
It should drop to the bottom o{ the bore under its
own weight. lf not. repeat step 4 then retest.
VALVE BODY
Remove the valve and thoroughly clean it and the
valve body with solvent. Dry all parts with com
pressed air, then reassemble using ATF as a
lubricant.

Driveshafts
Inspection
Driveshaft Boot
Check the boots on the driveshaft for cracks,
leaking grease or loose boot bands.
lf any damage is found, replace the boot
Danos.
Looso Splines
Turn the driveshaft by hand and make sure the splines
and joint are not excessivelV loose.
lf damage is found, replace the inboard joint,
Twistod or Cracked
Make sure the driveshaft is not twisted or cracked.
Replace it if necessarv.
damage,
and boot
Removal
Loosen the wheel nuts slightly.
Raise the front of car and support it with safety
stands in the proper locataons (see section 1),
Remove the wheel nuts and front wheels,
Drain the transmission oil or fluid (see section 13 or
14).
NOTE: lt is not necessary to drain the differential oil
when the left driveshaft is removed.
Raise the locking tab on the spindle nut, then
remove the nut.
WHEEL NUT
6. Remove the self-locking nut and self-locking bolt.
GAUTION: Roplaco th€ s€lt.locking bolts if you can
sasily thread a non€elf-locking nut prst thoir nylon
locking inserts.(lf should require I N.m (0.1 kgt.m, 0.7 lbf.ft) ol
torqus to turn lhs nut on the bolt).
Remove the damDer fork.

8.Pack the inboard joint with the ioint grease included
in the new driveshaft set.
Grease quantity; 120 - 130 g 11.2 - 4.6 ozl
9. Fit the inboard joint onto the driveshaft.
NOTE;
. Reinstall the inboard joint onto the driveshaft by
aligning the marks on the inboard ioint and the
rollers.
. Hold the driveshaft so the inboard joint points up
to prevent it from falling off.

10.Adjust the length of the driveshafts to the figure
below. then adjust the boots to halfway between
full compression and full extension.
NOTE: The ends of boots seat in the groove of the
driveshaft and joint.
Left: 475 - 480 mm {18.7 - 18.9 inl
Right: 475 - 480 mm (18.7 - 18.9 inl
lnstall new boot bands on the boots, and bend both
sets of locking tabs.
Lightly rap on the doubled-over portions to reduce
their height.
