Tighten hub nut (22) to a torque of 150 Nm at the same time
rotating the hub and drum.
Locate the locking collar (23) onto the dowel on the hub nut noting

and turn the hub nut 2 1/2 holes anti-clockwise.
Reverse the collar and re-locate it onto the repositioned hub nut
dowel.
Fit the lock nut (24) and tighten using a torque of 400 Nm.
Check whether the hub rotates freely and without excessive end-
float (adjust if necessary).
On the wheel hub, replace the O-ring (39) for the snap fastener of
the wheel cap.
Push on the hub cap and check that it is securely seated.
Measure the voltage output on the ABS sensor cable using a
voltmeter (approx. 100 mV), whilst turing the brake drum.
Check the sensor, if necessary.
