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.
