My problem at the moment is that the cv nut holding the hub in isn't coming off and I can't get the cv or axle out. How can I get any of it off? not even my impact gun can get it off. there's nothing left on it, i.e. rotor caliper etc, and it's sitting on stands so yeah...

My b18 cv's are looking really worn and tired as well and I was wondering if it's better to just replace the old axles completely, or to just replace the cv's? (even though I can't get it out at the moment...)
