How do I find the Axle Ratio and Limited Slip?

To determine the axle ratio of your vehicle, locate the two-digit axle code first, then use your vehicle's towing guide to find the axle ratio that corresponds to that code. If your vehicle has a limited-slip differential, it will be noted as Limited Slip.

The instructions below will walk you through the steps.

Step 1: Locate the Axle Code

1. View the Safety Compliance Certification Label on the driver's side, front or rear door panel.
2. Find the word AXLE under the bar code.
3. Find the two-digit code under AXLE.
 

Step 2: Find the Axle Ratio

1. Visit the Recreational Vehicle (RV) & Trailer Towing Guides page on the Ford Fleet website.
2. Select the Towing Guide for your vehicle's model year. 
   
   Note: Rear axle ratios are available for 2008 and newer models. If you need the rear axle ratio for a vehicle produced before 2008, contact our Customer Relationship Center via Live Chat or call us at 1-800-392-3673.
    
3. Refer to the Axle Ratio table to determine your rear axle ratio and limited slip.
