I have a power steering fluid leak. seems to be coming from the pump im guessing, as there is some fluid on my belt. I have read that its rare that the P/S pump will need to be replaced only a reseal is needed for p/s leaks as I have already attempted to use Lucas' p/s fluid with stop leak to no avail. Is it very difficult to reseal the p/s pump? Anyone ever perform this task? Please help and advise, thanks.
