Removing your CV isnt too bad, but you should replace it, cuz if it breaks, quess what, your not going anywhere but too the phone to call a tow truck. I havce busted several axles/CV's. Easiest thing to do is buy the entire axle cv assembly, then its a matter of taking off your wheel, disconnecting the hub so you can slide the splines from the axle out of the hub assembly. Dont actually remove the hub, just remove it at the lower points and let it hang from up top, then slide the splines out, and then pull the axle out of the trans. You will need to have a pan under teh trans at this point as it will leak fluid, and you will need a new axle seal. Remove the old seal, put new one in, put new axle in and bolt it all back together. That is the jist of it. Good luck.
