Summary
This bulletin supersedes the previously issued bulletin(s) listed below. The changes are noted in Red. 02-001/26 04/29/26 Some customers may complain that an abnormal noise is heard from the front suspension when driving on rough road surfaces or when passing over speed bumps. This is caused by insufficient heat resistance of the bushing material under specific operating conditions, resulting in cracking and fluid leakage in the front lower arm bushing. To eliminate this concern: The bushing material has been changed to a heat-resistant material. The bushing shape has been modified to reduce deformation. The damping characteristics of the front lower arm bushing have been modified. REPAIR PROCEDURE 1. Verify the customer concern. If noise is detected, replace the front lower arm (rear side) according to the instructions in MGSS. CX-90 (FRONT LOWER ARM REMOVAL/INSTALLATION) CX-70 (FRONT LOWER ARM REMOVAL/INSTALLATION) If NO noise is detected, this TSB is NOT applicable. NOTE: Perform repairs on the affected side only.
