It sounds like the ball joints or tie rods are bad. I had the front end checked and the mechanic said everything is tight. The problem might be a loose caliper, he claimed. I ordered new caliper mounting bolts, rubber and metal washers, and any other caliper mounting hardware I can find. Was going to work on my c4 this winter, but I'd rather wait for a nice spring day and work on it outdoors in the sunlight. I'd like to thank Canadian Corvette for always staying in touch with me. Your web site and the members are awesome.
