right now i currently have no power assist at all,at first i thought it was a pump failure untill i took it apart and found that the fins are in good shape along with the springs and seals.there is no leaks at all under the car and the resivior tank fluid level it up to the line over the past year.is it possible that somthing busted in the rank internaly causing low presure? or can a power steering flush help get it fixed maybe because of old or burned fuilds? please let me know.
