Hi guys I am new to posting and stuff so I tried searching and I couldn't find the answer I was looking for. anyways here it is I just read a post that said a 2003 FX4 has a limited slip axle I have never heard this before. I just wanted to know if this is true thank you in advance for any answers.

 

It may have a limited slip. To verify look at the code on the door sticket. If it is a letter and a number (ex. H9), it is limited slip. If it is 2 numbers, it is an open diff.
