i dont know, i dont have 4wd. i can tell you though if its like utvs i used to work on, take wheel off remove the spindle nut and the ball joint nuts, pop the ball joints apart with either the pickle fork or not reccommended but you can take the ball joint nut and put it on there alittle and whack it with a hammer but be careful not to damage threads. then you should be able to pull the hub off the shaft and then with a quick jerk the shaft should pop out of the diff, it has a spring collar to hold it in place and it can be tough to get out. oh yeah you should also take the tie rod end ball joint off too. you might have to remove brake line but prolly wont. to get shaft back in just put shaft up in the hole and give it a good push till it pops in place then reverse removal instructions to reassemble. may not be exact instructions but its a good start i hope. shadetree or helmut should know alot more than me so if they chime in, you can take it to the bank.
