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 Requesting a Door Jamb 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.
