Summary

Some vehicles may exhibit a knocking / squeaking noise from the front shock absorber when driving on rough roads and/or when turning the steering wheel while the vehicle is stopped. The noise may be due to:•upper front strut bearing (a) damage. (cx-5 and mazda6)•stick/slip between the front strut bearing and coil spring. (cx-3, cx-5 and mazda6)•the bump stopper (c) may be contacting the strut bearing when the front shock absorber is compressed, causing a popping noise. (mazda6 only)•the front lower arm bushing (d) is making a stick-slip noise in wet road conditions. (cx-5 and mazda6).to eliminate the noise, the following mass-production changes have been made:1. The material and production method of the front strut bearing (a) has been changed. (cx-5 and mazda6)2. A protector has been installed onto the coil spring. (cx-5 and mazda6)3. The shape of the bump stopper (c) will be modified in the future. (mazda6 only)4. The shape of the coil spring has been changed. (cx-3 only)5. Friction of the lower arm bushing has been reduced by adding a dry coating. (cx-5 and mazda6)note:the piston rod nut (b) requires replacement.
