Yes its pretty easy.
You might want a puller to get the steering wheel off, and you need a torx bit, i forgot the size, t30 maybe?
and a 18mm socket IIRC.
you could also consider swapping the clock spring to avoid chopping up ALL of your wires, but repining or splicing your cruise control wires should be that bad either.
Are you sure its an 18mm??? I'm pretty sure its a 19mm nut holding the steering wheel on the steering shaft
