I am a new 4wheeler owner and new on here as well so hello all. I purchased my 00 sportsman 500 4×4 used and it needs a little work. I was riding it around the house and twice it made a pop at the front and the bars jerked left for a fraction of a second it did this twice. Then while riding down the road it just started pulling left like I had to fight to keep it straight till i could get stopped. i limped to the drive way and then put it in reverse and backed up a little put it back in drive. i then pulled it into he garage and did not feel it pulling left. Now I am a decent mechanic and noted that the right front CV axle boot is busted and grease is all over I feel that this is the culprit but want to ask if it could possibly be something else as I have not really worked on ATVs

Thanks in advance
