FRONT WHEEL ALIGNMENT CHECK AND
ADJUSTMENT

M1331000900057

Required Special Tool:

•

MB991004: Wheel Alignment Gauge Attachment.

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

Standard value: 0

±±±±

3 mm (0

±±±±

0.12 inch)

NOTE: If the toe-in is not within the standard value, adjust the
toe-in by undoing the clips 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.
For each one turn of the left and right tie rods, the toe-in will be
adjusted by approximately 1

°

05' (per wheel).

Use a turning radius gauge to check that the steering angle is
at the standard value.

CAUTION

Never subject the wheel bearings to the vehicle load when

If the camber is outside of the standard value, perform the
following adjustment procedures.
1. Estimate how much additional camber adjustment is

required. Using the table below, select the camber adjusting
bolt, and then replace the knuckle and strut assembly
connection bolts (upper bolt, lower bolt) with the selected
bolts.

NOTE: If the camber adjusting value that is required is greater
than 1
