SENSOR ROTOR INSPECTION
Check rotor serration (teeth) for being missing, damaged or
deformed.
Turn wheel and check if rotor rotation is free from eccentric-
ity and looseness.
Check that no foreign material is attached.
If any faulty is found, repair or replace.
INSTALLATION
Reverse removal procedure for installation noting the following.
Check that no foreign material is attached to sensor (1) and
ring.
Be sure to install wheel speed sensor and its bolt at the cor-
rect (upper) position as shown in figure.
Tighten sensor bolt to specified torque.
Tightening torque
Sensor bolt (a) : 10 N·m (1.0 kg-m, 7.5 lb-ft)
Check that there is no clearance between sensor and rear
axle shaft.
