How can you tell if you have trac lok or not.

Hey guys, first off let me apologize because I know there are a number of threads on this but none of them end with a definite answer.
I need to change the fluid in my differentials, but before I do I need to see if need the friction modifier for the trac lok system(if there is one)
Below is my build sheet.

Ive learned that the Dana 35 is the same as the 175mm. But have found no definite way to find out. Even jacking it up won't give a definite answer because if I do have lockers, and the clutch plate is broken it would act like an open differential, and the tires would spin in opposite directions, correct?

Please help, I'm the original owner so no mods have been done.
Specs : 98 tj sport 4.0l lots of miles.

Is this a rubicon? If not, do you have a switch for lockers, or at the hubs?

DSA is the code for Trac Lok I don't see it on your list. So don't worry about it.

No worries about whether you need to add friction modifier or not, probably 99% of the gear lubes on the store shelves contain it anyway. It's included in most gear lubes since the additive is compatible with all axles. You'd have to look hard for a gear lube that doesn't already contain it.
