I jacked my van up and noticed quite a bit of fluid on my steering gear box. I then checked my PS resevoir and there was hardly anything in it.( i could see fluid in the bottom of it but nothing touching the dipstick) i havent heard the PS pump whine at all and my steering is very easy. Im wondering if i should get a new gear box or try and rebuild this one, it just blows my mind i havent noticed any side effects!?
