Some here recommended to me to just buy a cheap axle - I got mine from Adv. Auto for about $65 with online coupon. It was pretty easy to change as far as axles go.

I've gone the boot changing route on another vehicle and for my time and money, I'll put in a whole new axle rather than mess (MESS!) with re-booting a used axle.
