Adjustment
1) Loosen the left and right side steering tie-rods lock nuts.
2) Turn the left and right tie rods equal amounts until the
toe-in is at the specification.
Both the left and right tie-rods are right-hand threaded. To
increase toe-in, turn both tie-rods clockwise equal amounts
(as viewed from the inside of the vehicle).
3) Tighten tie-rod lock nut.
Tightening torque:
83±5 N⋅m (8.5±0.5 kg-m, 61.5±3.6 ft-lb)
CAUTION:
Correct tie-rod boot, if it is twisted.
NOTE:
Check the left and right wheel steering angle is within
specifications.

4. REAR WHEEL TOE-IN (FWD MODEL)

Inspection
1) Using a toe-in gauge, measure rear wheel toe-in.
Toe-in: 0±3 mm (0±0.12 in)
2) Mark rear sides of left and right tires at height corre-
sponding to center of spindles and measure distance“B”
between marks.
3) Move vehicle forward so that marks line up with front
sides at height corresponding to center of spindles.
4) Measure distance“A”between left and right marks.
Toe-in can then be obtained by the following equation:
BA = Toe-in
G4M0483

Adjustment
1) Remove cap from lateral link and loosen self-locking
nut.
CAUTION:

When loosening or tightening adjusting bolt, hold
the bolt head and loosen self-locking nut.

Replace self-locking nut with a new one.
2) Using two wrenches, turn adjusting wheel and adjusting
bolt equally in opposite directions so that toe-in is at the
specification.

NOTE:

When left and right wheels are adjusted for toe-in at the
same time, moving one scale graduation changes toe-in by
approximately 4 mm (0.16 in).

Turn adjusting wheel and adjusting bolt equally in oppo-
site directions so that same scale graduations are posi-
tioned directly above center of the adjusting bolt.
3) Tighten self-locking nut.
