SERVICE ADJUSTMENT PROCEDURES
REAR WHEEL ALIGNMENT INSPECTIONN17FAAC
The rear suspension assembly must be free of worn, loosen or
damaged parts prior to measurement of rear wheel alignment.
Standard value:
Toe-in (Left-right difference)
Of3 mm (Of.118 in.)
Camber-45’ + 30’
NOTEThe rear wheel alignment is set at the factory and cannot be
adjusted.If toe-in or camber is not within the standard value, replace
bent or damaged parts.
WHEEL BEARING END PLAY ADJUSTMENT,7FBA0
1.Inspect the play of the bearings while the vehicle is jacked
up and resting on floor jack.
2.Remove the hub cap and then release the parking brake.
3. Remove the caliper assembly and the brake disc.
4. Check the bearing’s end play.
Place a dial gauge against the hub surface; then move the
hub in the axial direction and check whether or not there isend play.
Limit: 0.01 mm
(.004 in.) or less
NOTE12AO531If the limit value is exceeded, the lock nut should be
tightened to the specified torque and check the end play
again.
5.Replace the rear hub bearing unit if an adjustment cannot
be made to within the limit.
