Replacing front CV Half Shaft Assembly

[PaHumBug]

Hey guys, the stealership just told me that my axle seal on the front diff is leaking, and the "axle spacer" on the opposite side is broken (I have a 6 inch fabtech lift so the spacer isn't stock). How hard is it to change those seals and the spacer? Is it just a matter of taking some bolts out and pushing that end of the axle aside? Or will the whole front end need torn apart?
Thanks
