Has anyone changed that boot on a 2003 Arctic Cat 400?
Do I have to drop the skidplate on the axle?

 

Go on youtube and do a search, they show how to change a boot,all ATVs are done much the same way.there is a good one of a guy doing the front boot of a Arctic Cat,there done the same as the rear. Not a bad job, good luck.

Here it is YouTube - Changing ATV CV boot on 2003 Arctic Cat 400 Automatic Remember back is done about the same way.
