        New Ring and Pinion Break-In Procedure

        1. Read the entirety of this procedure before driving on the new ring and pinion(s).
        2. Use only petroleum gear oil (not synthetic).  We recommend 85W-140 Lucas. 
        3. NO towing, NO heavy loads, NO hard acceleration, and NO other driving that will introduce heavier loads on the gear set(s) than cruising at a constant speed on level ground.
        4. Drive 10 miles and do not exceed 40 MPH (listen for abnormal noises or anything else you may notice that could be causing damage inside the differential housing).  Stop and check the housing temperatures near the pinion bearing and carrier bearing locations.  Temperatures must not exceed 190°F (we use a Fluke IR hand held thermometer).  Allow the differential to cool before proceeding.
        5. If the trip resulted in temperatures not exceeding 190°F then add 5 miles to the previous trip distance and perform the same process.  Repeat until there is more than 100 miles total of break-in trips.

          If the trip resulted in a temperature 190°F or more, then continue to drive 10 mile trips.  Perform the same process until temperatures are below 190°F.  If you reach 100 miles of break in trips and the differential is still reading over 190°F, then an inspection inside the differential for an incorrect installation and/or component failure should be performed.
        6. Once 100 miles total has been reached with break in trips, and not exceeding 190°F, you may increase your speed to 50 MPH and make 50 mile maximum trips.  Stop and check temperature to monitor that it doesn't exceed 190°F.  Allow it to cool before continuing.  Repeat until the break-in trips total 300 miles or more.
        7. Drain the fluid.  Observe if there are any large chunks or other abnormalities.  Small metal "flakes" (glitter looking) is normal to an extent.
        8. Inspect the differential components for any other abnormal wear, damage, defects, etc.
        9. Refill with new non-synthetic fluid.
        10. Continue to drive with easy acceleration and a maximum speed of 65 MPH until 500 miles of total break-in trips has been reached .  Monitor temperatures for the 190°F maximum and allow to cool if it's near that temperature.
        11. Once above 500 miles, with no issues, the vehicle can be driven normally.
        12. Change the gear oil every 30,000 miles or sooner if contaminants are introduced or suspected.
