Summary

Some vehicles may exhibit one or both of the following noises from the front suspension: 1. A creaking noise from under the front of the vehicle (front lower arm bushing) when driving over bumps at approximate 12 - 25 mph (20 - 40 Km/h). The noise occurs when the road surface is wet or after the vehicle has been washed. The noise becomes more noticeable as the bumps get higher. The creaking noise is caused by the front lower arm bushing (A) making a stick-slip noise during wet road conditions. 2. A clunking noise from the front coil spring when driving over bumps. The clunking noise is due to stick-slip between the front strut bearing (B) and the coil spring (C).To eliminate the noise, the following mass-production changes have been made: 1. The coating treatment of the lower arm bushing has been changed to reduce friction and prevent stick-slip. 2. Protectors have been installed onto the coil springs to prevent stick-slip.
