I saw two different mechanics, one was at the Ford dealership, and both gave the same explanation for my problem. The steering column has red grease inside that over time (it's a 1995 with 173,000 miles) and with heat (I live in Louisiana) will sometimes leak out. They said that this was the problem. All that I could do was to clean up the mess until it all eventually leaked out and that the grease did not need to be replaced. So your diagnosis about the steering column leak is correct. Thanks for your help.
