Here's a link to the Polaris website so you can see a diagram of your sled.
To replace the radius rod ends on the front, remove the old one from the spindle, remove it from the rod. If you broke the rod too, you will have to remove the other end, which is a real bugger, especially if your sled has a belly pan protector. When you install the new rod end, make sure the rod length remains the same.
If you broke the end of the steering tie rod, that rod has two Heim joints that are opposite threaded. If you bent that rod, you will have to gain access to both ends of the rod to loosen the lock nut. Rod length is even more critical, any variation will mess with the ski alignment and can cause handling problems.
