Break-In Procedure
- 1. Insure that the axle has been filled to the correct level with
proper hypoid lubricant before driving the vehicle.
The oil rating must be GL5 or higher.
- 2. Bring the axle to normal operating temperature by driving the
vehicle (unloaded) for approximately 15 to 20 miles. Do not
run full throttle accelerations or create any shock loads.
- 3. Let the axle assembly cool completely.
- 4. For the next 200 miles of operation, drive gently, without any
heavy loads.
- 5. If trailer towing is intended, an additional cycle of 200 to 300
miles of break-in is required without the trailer. This is important!
To properly break-in a new gear set, a minimum of 500 miles of
driving is essential before towing.
