Stuart Ake , California - 1986 Toyota Camry
A question about a noise. His car makes a 'metallic quacking' sound, from the right front wheel area. Noise changes with speed of car, and gets worse on turns. Mechanic said it was control arm, replaced, but noise got worse. Control arm was bogus--it's non-rotational. Problem is likely either a bad wheel bearing, stuck brake caliper, worn rotor, or bad tire. Go back to mechanic and get him to work on it again for free, since he blew it on the control arm.
