ON-VEHICLE SERVICE

WHEEL ALIGNMENT CHECK AND ADJUSTMENT

Measure the wheel alignment with the vehicle parked on a level surface. The front suspension, steering system, and wheels should be serviced to normal condition prior to measurement of wheel alignment.

TOE-IN Standard value:

At the centre of tyre tread 0±3mm Toe angle (per wheel) 0_00’±08’

Clip

1. If the toe-in is not within t h e standard value, adjust the toe-in by undoing the clip and turning the left and right tie rod turnbuckles by the same amount (in opposite directions).

Stabilizer bar bracket mounting bolt removal and installation

33100090267

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. Use a turning radius gauge to check that the steering angle is at the standard value. (Refer to GROUP37A - On-vehicle Service.)

TOE-OUT ANGLE ON TURNS

To check the steering linkage, especially after the vehicle has been involved in an accident or if an accident is presumed, it is advisable to check the toe-out angle on turns in addition to the wheel alignment. Conduct this test on the left turn as well as on the right turn.

Standard value (inner wheel when outer wheel at 20_):

<SPACE RUNNER> 22_10’ <SPACE WAGON> 21_50’

NOTE

1. Camber and caster are preset at the factory and cannot be adjusted.

2. If camber is no t within the standard value, check and replace bent or damaged parts.

3. For vehicles with aluminium type wheels, attach the camber/caster/kingpin gauge to the drive shaft by using the special tool. Tighten the special tool to the same torque 196 - 255 Nm as the drive shaft nut.

Caution To prevent the wheel bearing from damage, never subject the wheel bearings to the vehicle load when the drive shaft nuts are loosened.

BALL JOINT DUST COVER CHECK

33200860090

1. Check the dust cover for cracks or damage by pushing it with finger.

2. If the dust cover is cracked or damaged, replace the upper arm assembly, compression lower arm assembly, lateral lower arm assembly or stabilizer link.

NOTE Cracks or damage of the dust cover may cause damage of the ball joint.
