/ 4. SELF-LOCKING NUT
(I) Hold the stabilizer link ball studs with a wrench and
install the self-locking nut (A).
(2) Holding the stabilizer link with a wrench, tighten the
self-locking nut
(B) so that the protrusion of the
stabilizer link is within the standard value.
Standard value: 5
- 7 mm (197 - .276 in.)
2. INSTALLATION OF STABILIZER BAR BRACKET
(1) Align the bushing (L.H.) with the stabilizer bar marking
end and temporarily tighten the stabilizer bar bracket
(L.H.).(2) In this condition, mount the stabilizer bar bracket

SERVICE POINTS OF REMOVALM34MBAC
1.REMOVAL OF REAR SPEED SENSOR ABS>Caution
Be careful when handling the pole piece at the tip of the
speed sensor and the toothed edge of the rotor so as
not to damage them by striking against other parts.
2. REMOVAL OF CALIPER ASSEMBLY
Remove the caliper assembly and suspend it with a piece of
wire.
8. REMOVAL OF REAR ROTOR ABS>Caution
Care must be taken not to scratch or scar the rotor’s
toothed surface, and not to drop it.
If the rotor’s toothed surface is chipped or the rotor is
deformed, it might not be able to accurately sense the
wheel rotation speed and the system as a result might
not perform normally.

NOTE
12FOO21Left wheel: Clockwise (0 camber)

(0 camber)
The difference between the right and left wheels
shoiuld be 30’
or less.

NOTELeft wheel: Clockwise (toe-in)
Right wheel: Clockwise (toe-out)
The difference between right and left wheels should be 3 mm
(.12 in.) or less.
One graduation changes toe by about 2 mm
(.08 in.).
Caution
1. Adjust the eccentric cam bolt within 90” from’ the
central position.
2.Adjust camber and toe, in that order, and, if camber is
adjusted, be sure to adjust toe also.
3.For the vehicles with 4WS, make the adjustments with
the 4WS tie rod end disconnected from the trailing arm.
