Some vehicles may exhibit a crack on the front shock absorber dust boot \(A\). This may be caused by dust boot insufficient resistance to cold. The shape and material of the dust boot has been changed to improve the resistance to cold.
- [02\-010\-16\-3170](/bulletins/10185907.md), 2021-01-28, Service bulletin: STEERING; SUSPENSION:FRONT:SHOCK ABSORBER. 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.
- [02\-016\-18\-3495](/bulletins/10145247.md), 2018-10-09, Service bulletin: SUSPENSION:REAR:SHOCK ABSORBER. Some vehicles may exhibit a rattle noise from the rear of the vehicle while driving. The noise may be caused by a rear shock absorber mounting bracket that is heavily corroded and broken. Due to insufficient durability of the bracket in certain environments, such as where road salt is used, corrosion and breakage can occur. To eliminate this concern, the material and the shape of the bracket \(service parts\) has been modified.

Some customers may complain of signs of oil on the struts or shock absorbers. In most cases the oil that is present is normal, and a result of the oil that remains on the shaft during the normal sweeping process of the shaft seal. Follow the inspection guidelines to determine if the condition is a result of the normal sweeping process or a failure of the shaft seal.
- [02\-002\-18\-3300d](/bulletins/10129564.md), 2018-03-05, Service bulletin: SUSPENSION:FRONT:SHOCK ABSORBER. Some vehicles may exhibit a knocking / squeaking noise from the front shock absorber when driving onrough 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. \(CX\-5 and Mazda6\) Squeak type noise 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 creak type noise in wet road conditions. \(CX\-5 and Mazda6\).Front Shock Absorber Front Lower Arm 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.
