A truck’s axle code tells you what type of differential and ratio you have. For example, based on Ford axle code 39, it looks like you have a Ford F250 with a 3.55 non-limited slip differential. A non-limited slip differential is equipped with electronic operation control, so it only offers partial locking on slippery ground. Unfortunately, that means if you’re driving in foul weather or on rough terrain, your wheels might not get as much traction. If you think your axle might need repair or have questions about how it works, it’s best to reach out to a mechanic. Problems with the axle can be pretty serious, and may even cause your tires to get locked in place!
