Ring and Pinion Break In Procedures

Properly breaking in your new gears is very important makes a significant difference between encountering gear-related issues down the line and enjoying trouble-free driving for years to come. By adhering to the recommended break-in procedures, including the specific requirements for towing, you ensure that the gears are thoroughly seasoned and hardened, promoting their longevity and reliability.

To ensure the proper break-in of new gear sets and prevent overheating damage, it is crucial to follow these guidelines:

1. Drive light-footed at low speeds for the first 15 to 20 miles:

Take it easy and baby the vehicle during the initial 15 to 20 miles. Afterward, stop and allow the differential to cool down before continuing. Repeat to 100 miles.

2. Avoid heavy acceleration:

During the first 100 miles of the break-in period, avoid any sudden or extreme acceleration and steep hills, as this can put excessive stress on the gears.

3. Change the gear oil after the first 500 miles:

After driving approximately 500 miles, it is advisable to change the gear oil. This helps remove any metal particles or phosphoric coating that may have been shed by the gear set during the break-in period.

4. Drive at least 500 miles before towing:

To retain the warranty on the gears, it is recommended to drive the vehicle for a minimum of 500 miles before towing any heavy loads.

5. Break in the gears when towing for the first time:

If you need to tow a load for the first time, follow this procedure: Drive a very short distance (less than 15 miles) with the full load, then stop. Allow the differential to cool for approximately 20 minutes before proceeding. Repeat this process two more times, covering a total distance of approximately 45 miles, to fully break in the gears.
