Total Toe-in Adjustment
1. Center the steering wheel and confirm that the vehicle wheels/tires are pointing straight.
2. Loosen the left and right tie-rod end locknuts and turn the tie-rods equally. Both tie rods are right threaded, so
turning the right tie-rod toward the front of the vehicle and the left toward the rear increases toe-in.
Note
•Turning both tie-rods one complete turn changes toe-in by about 6 mm {0.24 in} (0°36').
3. Tighten the tie-rod end locknuts to the specified torque.

Caution
•Performing the following procedures without first removing the ABS wheel-speed sensor may
possibly cause an open circuit in the harness if it is pulled by mistake. Before performing the
following procedures, remove the ABS wheel-speed sensor (axle side) and fix it to an appropriate
place where the sensor will not be pulled by mistake while servicing the vehicle.
1. Remove the rear auto leveling sensor and harness.
(See T–20 REAR AUTO LEVELING SENSOR REMOVAL/INSTALLATION.)
2. Remove the middle pipe.
(See F1–30 EXHAUST SYSTEM REMOVAL/INSTALLATION.)
3. Remove in the order indicated in the table.
4. Install in the reverse order of removal.
5. Adjust the headlight zeroset.
6. Inspect the rear wheel alignment.
