Does a 2004 Ford Expedition w/ towing package have a limited slip differential?

I have a 2004 Expedition, and I was wondering whether or not it has a limited slip differential. It has the HD towing package, but I'm not sure about the diff. Any help will be greatly appreciated.Does a 2004 Ford Expedition w/ towing package have a limited slip differential?
Most likely it does. There are a couple ways to find this out if you are not the original owner and have the build sheet. 1. crawl under the rear of the vehicle and look for the axle tag attached to a bolt on the housing. If, for example, it lists 3.54 as the ratio, it is non-locking; if it lists 3L54, then it is a locking axle. 2. go to Motorcraft.com and put your VIN in to get a list of what the vehicle is equipped with. 3. Give me the VIN and I can run it for you.Does a 2004 Ford Expedition w/ towing package have a limited slip differential?
Yes or no is the answer. The limited slip rear axle was an option on that truck. You can have the trailer tow package with or without it.
