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.
