I'm working on my buddy's Foreman 400. His boot over his top CV joint on the front came loose and got packed with mud. I have gotten it completely detached from everything but the differential. I pulled and pried, but I cant get it to turn loose. Does anybody know the trick to getting this thing to turn loose.

 

It just pulls straight out, give it a good sharp yank or 2 or 3, they dont always come out easilly.
