How to identify your axle ratio
There are a few ways to identify your 2020 Ford Transit's axle ratio:
-
Door-jamb sticker: The easiest way to find your axle ratio is to look for the Safety Compliance Certification Label on the driver's side doorjamb. Under the "AXLE" heading, you'll find a two-digit code.
-
Axle tag: You can also find the axle ratio on a tag bolted to the differential housing. The ratio will be stamped on the tag (e.g., 3 31 for a 3.31 ratio).
-
VIN decoder: You can use an online VIN decoder to find your axle ratio. Simply enter your VIN, and the decoder will provide you with a detailed build sheet for your vehicle.
Towing vs MPG impact
The axle ratio has a significant impact on both towing capacity and fuel economy. Here's a breakdown of how it works:
-
Numerically lower axle ratio (e.g., 3.31): This is better for fuel economy, as the engine doesn't have to work as hard to maintain speed. However, it's not ideal for towing heavy loads.
-
Numerically higher axle ratio (e.g., 4.10): This is better for towing, as it provides more torque to the wheels. However, it will result in lower fuel economy.
Common issues
While the 2020 Ford Transit is a reliable vehicle, there are a few common issues to be aware of:
-
Ring and pinion whine: Some owners have reported a whining noise from the rear differential. This is often caused by improperly machined gears and may require replacement.
-
Carrier bearing failure: The carrier bearings support the driveshaft and can fail over time. Symptoms include a vibration or rumbling noise from under the vehicle.
-
Limited-slip clutch wear: On models equipped with a limited-slip differential, the clutches can wear out over time. This can cause a chattering or grinding noise when turning.
