1st: There was a recall on early 500 foremans on the tie rod ends. Make sure your not part of that. They can run you vin at the dealership and see.
2nd: How many miles are on your ride? Tie rod ends will eventually wear out, mine went around 3200 miles. I was going down the trail and my inner tie rod popped off the ball. After looking closely the boot of the tie rod end had split which let dirt and grime get in and wear out the area wear the ball rests. I replced all at once because after I took them off I realized that the other boots were good but the grease had dried up in them. My suggestion is replace one, replace them all. You never now the others may seem alright now but you might be having to replace them next year.
