Look at the vehicle certification label on the driver's door. Under the bar code look for the word "AXLE". Directly underneath is a two digit code for your axle. If the code consists of two numbers, you have an open (non-limited-slip) differential. If it starts with a letter (often the letter "H") the rear differential is equipped with the optional limited slip feature. The second digit relates to the gear ratio.

Yes, now that you say that I remember Ford codes being that way years ago. I'm going to look at this 01 tomorrow and I wanted to know what I'm looking at. I don't want to buy a truck with 3.31.. Thanks again.
Any chance you'd know the codes for a 3.55 or 3.73? Or know where I can find them?
