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. • the bump stopper (c) may be contacting the strut bearing when the front shock absorber is compressed, causing a popping noise. (mazda6 only) 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) note: the piston rod nut (b) requires replacement.
