You can pick up a pump on ebay if thats the case otherwise if its just a bad hose or clamp your looking at a couple bucks and less than an hour or labor if you can do it yourself. That can't be fun driving a durango without power steering, i bet its fun backing out real slow without power steering. Mine ran out of fluid once and it was a pain in the as$.
it was fun...lol....i had to go a 2 days without it and it sucked. at work i couldnt even pull into a parking spot...i had to pull in as much as i could and then back up and turn the other way is much as i could then pull back in.. it was a b1tch.
