That can be a wide variety of issues for any 4 wheeler. Start with the basics by checking and testing all the steering components and ball joints. Even wheel bearings. All you need for that is a jack, a pry bar and two good arms. From there, tire check for balance and integrity. More info is required. Shake when braking? At what speed? While turning & or driving straight? Etc. Still no reason not to start with the basics. Did you align it after changing the tie rods?
