Only the Rubicons came stock with locking diffs, they have switches on the dash board to lock and unlock the diff.

This is what a Dana 44 looks like.

So more than likely I'm guessing you have the D35c rear axle. Too be sure you will have to go take a look.

Also, no 01s came with a locking diff option. 03+ Rubis were the first year to offer this in a Wrangler.

Can you say "Pa-boom"? Don't do it unless you get the Superior "Super 35" kit. Even then, I would suggest replacing the axle to a D44 or Ford 8.8 from an Explorer.
