pdf有說明避震器發出異音的原因: Some vehicles may exhibit a squeak, knock, rattle/chatter, or unusual noise from the front suspension or rear suspension when passing over a bump at a low speed or driving on an uneven road. This is may be caused by one of the following: - The front/rear stabilizer bushing. - The front or rear bushing of the front lower arm. - The right rear coil spring has shifted in the spring seat rubber and/or upper spring pocket in the rear crossmember,and causing the spring to rub against the crossmember. This noise will most likely occur with the rear seat occupied, and can sound like a knock when going over a bump or a rattle when driving at a steady speed over uneven road surfaces. The problem is the arc-welding bead in the spring pocket on the crossmember where it makes contact with the spring seat rubber is protruding too much, causing the spring seat rubber to be pushed out of position.
