What would cause power steering fluid to leak out of an input shaft seal?

Would replacing the seal fix this issue? I don't see why fluid is even entering the steering gear/shaft area anyways. I thought it doesn't. 2008 Honda Civic coupe

Input shafts are in the transmission.
Power steering leaks are usually at the hoses or at the bellow boots where the tie rods come out of the steering rack. Have a mechanic diagnose it for you.

  • What kind of power steering fluid? I have a 05 Hyundai elantra and the power steering fluid is red. Dark red, and a friend of mine told me to use Honda fluid in it when I replace it, I siphoned some out and put a bit of Honda fluid it but the Honda fluid is clear, is this a problem? And what kind of fluid should I use? He said the Honda fluid lubricates the system better than a generic multipurpose fluid. Its probly 1/2 Honda fluid now mixed with the old fluid.
  • Is the 1985 Honda CR 500 water pump gear shaft compatible with the 86-2001 Honda CR 500 water pump gear shaft? I have a 1985 CR 500 and the water pump gear shaft broke. It has been discontinued from Honda, and no one else has it. It is a metal gear. The one's for the 1986-2001 CR 500 are plastic. If I have to use plastic, I will. However, I prefer not to. If anyone knows where I can get the OEM 1985 Honda CR 500 gear shaft, I would forever be grateful.
  • Does power steering fluid get hot if the car is just running and the steering isn't being used? If the pump is just spinning, recirculating fluid and nothing else… Would it still get hot? I had to bypass the pump from the rack and have the fluid recirculate. Would the pump get hot from just spinning? I know 8th gen Honda's don't have a cooler for the power steering anyways.
  • Would a bad input shaft bearing noise present during certain rpms while jacked up? My honda civic makes a loud rattle during certain rpms (2000+rpm) in 1st and 2nd gear, it does have a bad isb but the rattle i'm not %100 if it is related to the isb. Should the rattle/grind also be evident if the car is jacked up if it had to do with the isb?
