Welcome to the best forum around .
How many hours are on your machine? If it were me, I would jack it up and spin the tires by hand while listening for the click. Are the boots damaged? Also, some units were made without the wheel stop when they first came out in 2004 and would go too far in sharp turns.
I do hope it isn't the front wheel joints but if it is , there are supposedly some good aftermarkets available at good prices from places like from atv superstore.
Also may be a good time to change oil in the front end and "hubs" when you get a chance. Good Luck ! bordercollie.
