NOISE FROM FRONT WHEEL HUB BEARING
PURPOSE
This bulletin contains information about improvements to the front wheel hub bearing for certain 2001-03 Montero vehicles.
BACKGROUND INFORMATION
Symptom
While driving, customers may notice a noise from the front wheel bearing(s).
Cause
This bearing noise may be caused by excessive bearing wear because of water penetration into the bearing.
Remedy
If you identify this condition, replace the hub and bearing assembly along with the castle nut with parts supplied in a new front wheel hub/bearing
assembly kit.
AFFECTED VEHICLES
2001-03 Montero built before 1/7/2003
Vehicles built after the above date have the new hub/bearing assembly and castle nut installed at the factory.
PROCEDURE
Refer to service manual Group 26 for hub & bearing replacement procedures.
When installing the new hub assembly, make sure the castle nut is tightened to the new torque value (200 +/- 10 Nm [147.5 +/- 7 ft-lb]). The new-style
castle nut is modified with a friction coefficient stabilizer and has a green color on its surface.
CAUTION:
The modified castle nut, washer, and lock pin cannot be re-used once the nut has been tightened
