ON-VEHICLE SERVICE

FRONT WHEEL ALIGNMENT CHECK AND 
ADJUSTMENT

M1331000900477

Measure wheel alignment with alignment equipment on a level 
surface. The front suspension, steering system and tires should 
be serviced to normal condition before measuring wheel align-
ment.

.

TOE-IN

Standard value: 0 

± 3 mm (0 ± 0.12 inch)

1. Adjust the toe-in by undoing the clip and jam nut, and 

turning the left and right tie rod turnbuckles by the same 
amount (in opposite directions).
NOTE: The toe will move out as the left turnbuckle is turned 
toward the front of the vehicle and the right turnbuckle is 
turned toward the rear of the vehicle.

2. Install the clip and tighten the jam nut to the specified 

torque.

Tightening torque: 52 

± 2 N⋅m (38 ± 2 ft-lb)

3. Confirm that the toe-in is at the standard value.
