My Ford Dealer told me that I need to change the power steering fluid on my 02 Explorer. He said it wasn't bright red anymore and recommend spending $110 to flush and refill the system. I said "no" because I've never had to replace the fluid in any of my cars. It isn't even in the manual as a maintenance item. I got it home and began thinking it couldn't hurt anything to change it every few years or so.

Does anyone know the proper procedure to change the power steering fluid?
