There are lots of possibilities, bent tie rod, worn bearings/rod ends/ball joints. If you can lift the front end up and see if anything has any movement in it. Might also help if you list the year and model of your quad.
Like Js7FIFTY said , lots of possibilities. Yes, more info would be helpful.
If you just need to do an alignment and don’t have worn, bent, or broken front end components, you can do that yourself. You can purchase a set of toe plates, or use a string to perform an alignment. The string alignment takes some skill because the setup/clearance/contact area of the string is tricky. There are plenty of videos on YouTube that will demonstrate ATV alignments. Personally, I would recommend chipping in with another ATV enthusiast and buying a set of toe plates, or buying It yourself.
Considering its age its likely just a worn out bearings in the hub or a ball joint assuming you haven't hit anything recently. If you lift up the front end you should be able to tell which by moving the tire and rods.
