INTRODUCTION: This bulletin announces the availability of new propeller shaft assemblies. The new parts incorporate a production change made to address a small number of reports describing a high-pitched, squeal-type sound heard under certain low-speed driving conditions in colder temperatures ( ~20 mph in midteens F). The center support bearing has been identified as the source of the sound. New bearings with additional grease capacity have been incorporated to address the concern. If the condition is confirmed, the propeller shaft assembly must be replaced as the center support component is not a serviceable part. PRODUCTION CHANGE INFORMATION: The new propeller shaft assemblies were incorporated into production on 12/13/2019 as follows: • Legacy: L3015103 • Outback: L3157240 • Impreza 4Dr: L3605024 • Impreza 5Dr: L3710036 • Ascent: L3443783 SERVICE BULLETIN ATTENTION: GENERAL MANAGER q PARTS MANAGER q CLAIMS PERSONNEL q SERVICE MANAGER q IMPORTANT – All Service Personnel Should Read and Initial in the boxes provided, right. © 2020 Subaru of America, Inc.
