Hi all. I need some help. My daughter is going to look at an 02 F150 FX4. I am not very familiar with that year. First thing that doesn't make sense to me is that the dealer said it has a 3.55 regular axle. I thought all the FX4's were at least limited slip. It is also listed as an XLT and Lariat. Are the Lariat and FX4 just added to the base XLT in that year? It has all the other stuff you would expect of each package. Lastly, if it is a regular axle and that is normal what are your experiences with this configuration concerning traction and MPG? Thanks.

 

Most likely they don't know it has the limited slip. When I put my VIN in the computer it also says XLT, so I believe that yes the lariat and FX4 packages are added on afterwards. My work commute is 20 miles consisting of 45-64 mph traffic with one or 2 stops. I average 15-16 MPG depending on my foot. As far as traction goes I have to get on it pretty good to spin in the rain. But I see that you live where it snows.

 

Look at the data sticker on the rear driver's side door jam. If it has a letter and number in the axle code area, its got limited slip. Two numbers is open diff. See http://www.fordf150.net/howto/decode.php

 

I just talked to the salesman and he checked the code. It is a 19 which is the 3.55 non limited slip. So I guess my question of how this traction is still stands. We get pretty decent winters in central MN so handling is going to be important. On another note how do you think this would to a two horse trailer? I'm thinking no problems.

 

Hard to tell on the trailer, but anything under 5000lbs isn't usually a problem for these trucks.

As far as winter handling, open diff. without limited slip usually handles a little better on slippery roads and aren't as likely to spin out.
