Symptoms and Conditions                                                 
On some vehicles, there may be a growling or abnormal noise heard from
the front wheels at speeds below 50 mph. The front axle oil seals in
the steering knuckles may allow an accumulation of water to remain
between the seal and bearing, causing the wheel bearing to rust and
fail prematurely.

Repair Procedure
To prevent water accumulation and rust from damaging the front wheel
bearings, the steering knuckle OIL SEAL has been DELETED.

Also, there is a new steering knuckle that has a machined 'drain' to
prevent any water accumulation.

1. If the vehicle falls within the VIN range and has a failed wheel
bearing/s, install a new steering knuckle WITHOUT THE OIL SEAL
and replace the wheel bearing.
