The dealer did the spring guard recall on my 98 Mystique last week when I took it in for a heater blower wiring recall. I didn't even know about the front spring recall until I started driving it home and noticed it clunked over every large bump. My 205/60R-15 tires were close enough to the guard that I could not even fit my little pinky finger between them, although I don't think that was causing the clunking noise.
I went back to the dealer earlier this week, complained of the noise and asked them to remove the guards. They said no, since it was a safety recall. They gave me the # of some Ford customer service center. Instead of going around in circles with them I dove home, removed them myself and tossed the guards in the trash.
