I own a 1991 Ford Explorer, and until just recently I have heard a clicking type noise coming from the front end of the car. The sound is coming from both wheels, all least that is what it sounds like. I am not sure what the problem is, I have taken it to Firestone on 3 seperate occasions, first they tightned the shock bushings, then they tightned the lug nuts on my rims, and finally they told me they had no idea what the problem was. So I am here to ask you guys if you could give me some insight on what you believe the problem may be, that would be awsome. And I just got my wheel bearings repacked about 5 months ago. Any info would be great.

Thanks Derek

Something caught in the wheel? Too much greese in the hubs? Something catching on the brake pads?
