Hi guys. New to the forum and need some help. I have a 2001 Sportsman 500 and it makes a horrible grinding sound when the front wheels engage. It sounds like it’s coming from the front left side. Is this typical when the 4×4 kicks on?

Also, when I am in high gear and am starting to move it struggles to move. When I give it gas to start moving, the 4×4 kicks in every time. It really struggles to start moving in 2wd when my handlebars aren’t straight. Any thoughts or ideas about what’s going on?

Any help will be greatly appreciated! Thanks!
