INTRODUCTION

This bulletin announces the design change made to the front strut assemblies to address cases of a rumbling and/or rattling sound coming from the undercarriage when going over bumps. The internal rebound stopper of the strut has been resized to avoid deformation. If the sound is duplicated, replace only the affected strut assembly as they do not have to be replaced in pairs.
