when replacing the power steering pump, VES compatable is how important?

What is your question?

i do not know if i have VES. it isn't becoming more difficult to steer but, the condition of the accessories is not promising. there is a circular, rubbing sound coming from that area. replaced idler pulley, which helped decrease sound a small amount. when up close to the p/s/p it isn't the rubbing noise but it is making a noise, almost like it's struggling. happens on every start up. whether it is a chilly florida 40 degree morning or hot afternoon. fades out a bit, but never really stops. and this is without the a/c on.
