97 Ford Explorer, How to tell if differential is locking or non locking?

I have a 97 Ford Explorer that the numbers are rusted off the nameplate on the differential. I need to know if the differential is locking or non locking so I can put the appropiate fluid with the appropriated differential. Is there anyway to find out if the differential is locking or non locking without the info on the tag?Thanks in advance.

place it on jack stands at the end you are checking, then with the trans in park if auto or in gear if standard and attempt to rotate one wheel the other wheel will spin the opposite direction if it is a non locking diff, or if the clutches are worn out. if it is a locking differential you will not be able to spin the tire with the trans locked.

Put one wheel on the gravel and one wheel on the pavement and "see"
