Introduction
This service bulletin announces a design change to the front strut assemblies to address a rumbling and/or rattling sound coming from the undercarriage when going over bumps.
Description of Design Change
The internal rebound stopper of the strut has been resized to avoid deformation.
Replace only the affected strut assembly as they do not have to be replaced in pairs.
Important Reminders
Always check for any open recalls or campaigns anytime a vehicle is in for servicing.
Refer to STIS for the latest service information before performing any repairs.
