Power steering gear box leaks (pictures)

Looks like the "input shaft seal". It can be changed with the steering box in the car but its not easy to reach.

You have to knock the roll pin out, loosen the bracket under the dash holding the steering column and pull the column out.

One way is drill a very small hole in the seal, and insert a screw that will "push" the seal out. Then install a new seal. I went through the steering column hole in the firewall to remove and install the seal.
