DESCRIPTION


There is a possibility that a snapping noise can be heard from the front end of these subject vehicles. This condition occurs while the vehicle is moving slowly (walking speed) in forward or reverse, with the steering wheel fully locked to either side.

This noise may be caused by the sticking and slipping of the wheel bearing inside the front wheel hub. To prevent this noise, lock-tight has been applied to the wheel bearing outer race before the bearing is pressed into the knuckle.

If you encounter a customer complaint about this noise, remove the wheel bearing from the knuckle, and install a new one with lock-tight applied to the outer race.
