I started to notice a thumb/thud type noise about a month ago when ever I would hit the brakes a little hard or go over some rough bumps. Now the car is doing it a lot more. It seems to come from the front driver wheel area. I just recently replaced the front brake pads and looked for any obvious trouble. Didnt see anything too bad or obvious to me. Any ideas? Car has the FRPP c-springs and MM caster camber plates, those where put on about 2yrs ago, no other front suspension mods or replacement parts done.
