Well, you really can't replace an inner or outer tie rod...they are one piece.
at the steering box end of the tie rod, both sides, you will see the rubber boot. Remove both clamps and slide the boot off the steering box towards the brake rotor.
The large clamp is PN 7080979 the small clamp is PN 7080978. I believe the small one is reuseable.
After you slide the boot off you will see the ball joint end of the tie rod that threads into the steering box rack. There are two flats on the socket portion of the ball joint. Use a 12 inch crescent wrench and remove it.
When you put the new tie rod in, be sure to use blue locktite on the threads of the socket portion.
You can probably reuse the small clamp. Most replace the large clamp with a good zip tie.
The Polaris parts book doesn't show the tie rods as available as parts, just the entire steering box.
I do have a set of stock tie rods I took off to put on Racer Tech HD tie rods, if you're interested, PM me and we'll see what we can work out.
