I need to replace my axle bearings and Im having a hard time removing the axle nuts. On the left side: does the inside nut loosen counter clockwise and the out side nut loosen clockwise? I have the wrenches but can't get them to budge!

 

Their off! Ok. Here's how to remove axle nuts on a Z400. Heat the hell out of the nuts till they turn red and use a big pry bar. Note: Standard threads.. counter clockwise to loosen both. Looks like they use a lot of thread lock during assembly.

 

lol, been there,done that.
