Hello, I have a question about my differential. How can I tell if it's limited-slip, and what are the dimensions? My truck is a 2004 Ford F150 Lariat 4WD Supercab.

The differential should have a tag on the rear cover, it that will tell you the gear ratio and if it has a locking differential. A dealer can run the VIN and get the as built data as well.
