Exorcised the steering gremlin from my Demon

Thank you for your post.
This came at the perfect time because I'm facing the same thing, and was going to order a new p/s box from firm feel. (stage 2 like you did)
One question though, did you rebuild the coupler at the same time?
I'm tired of driving a car that ''hunts'' all of the time like it had bias ply tires on it...
I actually had rebuilt the coupler last year along with the steering column. So now EVERYTHING is like new. If you rebuild your coupler and it does not have the wire clip to keep the seal in place, I would highly recommend getting the wire clip for it.
