Find a reputable alignment shop. Talk to other Jeepers in local clubs to find who they would recommend. Then go in for a 'check'. You can make it just a toe check.
With the leaf sprung front axle, if you haven't lifted it and used shims, you really can't 'adjust' the axle for better geometry, unlike that of a linked axle. If there are issues in handling after the toe check, you may have a bent axle or knuckle.
Many shops provide a yr alignment or couple yrs for special price. Look into that as well.
I recommend talking around, especially with other YJ owners. I had my front end aligned after lifting it slightly and used adj control arms. The shop stated my axle or frame was bent as they couldn't adjust the axle into the tolerances. I told them the arms are adj in length, they responded they don't adjust the length of the arms. That'll cost more. So I left.
