The outer boot on my driver's side rear axle is torn, needing repair. From what I've read the best solution is to replace the whole axle with a remanfactured or used axle. I've done most replacements on the car (clutch, alternator, starter, rotors, etc...) but not this.

How hard is this
What tools will I need
What are good (or bad) sources for a reman or used axle.

Thanks
