How do I find the Axle Ratio and Limited Slip of my Lincoln vehicle?

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.

Locate the axle code

1. Locate 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.
Door jamb label
