TOE-IN ADJUSTMENT
1. To adjust the toe-in angle, loosen the lock nuts on the
outer track rods and turn the outer track rods. Turn
both rods the same amount, to keep the steering
wheel centered.

MAXIMUM STEERING ANGLE
ADJUSTMENT
The maximum steering angle of the front wheels can be
adjusted with the stopper bolts under the frame side
members.
1. Position each front wheel on the turning radius gauge
in a straight-ahead position.
2. Set the parking brake firmly.
3. Adjust the inside wheel angle of each side with the
stopper bolts.
NOTE:
The maximum protruding length (L) of stopper bolt from
the lock nut should be 10 mm (0.4 in) or less.

3. After measuring dimensions A,B,C and D, make
adjustment in the following manner:

Measure the thickness (E) of the spring disc.
1.75mm (0.069in)y4 discs
4. Select the friction disc & plate so as to satisfy the
following equation:
{(A-B)+C}-(D+E)=0.06-0.20mm (0.002-0.008in)
Also, the total size difference of the friction disc &
plate and spring disc should be 0.05mm (0.02in) or
less.

Backlash adjustment of the side gear in
the direction of the shaft
1. Measuring the depth of the differential cage.
(F±B): 82.03 mm (3.23 in)
(G): 12.03 mm (0.47 in)
425RS066
2. Measuring the dimension between the thrust washers
at both ends.

Assemble the side gear, pinion, pinion shaft,
pressure ring and thrust washer, and pressing the
pressure ring to±the pinion shaft in the direction of
the shaft to make the clearance 0.

Have the side gear contact to the pinion to make the
backlash 0.

Measure the dimension (H) between thrust
washers at both ends.
