This bulletin applies to 2010-2014 Subaru Legacy and Outback models. In response to isolated reports of cracked or broken ABS wheel speed sensor harness retaining clips caused by reaction with acids used in some wheel cleaners, the clip material has been changed to polypropylene (PPC).
The new retaining clips can be identified by the molded-in >PP < as shown in the photo. There are two clips on each sensor harness. The new clips are available as part number SOA635142.
