My 98 G. Caravan AWD has been leaking ps fluid for a couple months. Looking at it, it's hard to tell where it's coming from - return hose, pressure hose or pump and reservoir. Also, access is horrendous. With 243K miles on it should I just bite the bullet and order all the parts? What's the best way to access the parts - I don't want to mess with the exhaust and break bolts!
