Filing in context
The Drive shaft is the most frequently cited component category in this archive, appearing in 7 of its 4,890 filings. This filing is one of 17 Subaru notifications from 2023 in this archive. For scale, 3,625 of the 4,890 filings in this archive report a larger number of affected vehicles.
Defect
On some front drive shafts, improper heat treatment during the manufacturing process causes cracks to form on the outer race surface, resulting in insufficient strength. As the cracks propagate during use, the outer race breaks and power transmission is lost. In the worst case, the transfer clutch is damaged and the vehicle becomes inoperable.
Corrective action
Inspect the left and right front drive shafts on all vehicles. Replace any front drive shaft from the affected manufacturing lot with a conforming part.

状況
フロントドライブシャフトにおいて、製造工程における熱処理が不適切なため、アウターレースの表面に亀裂が発生し、強度が不足しているものがある。そのため、使用過程で亀裂が進展するとアウターレースが破損し動力伝達不良となり、最悪の場合、トランスファクラッチが損傷し、走行不能に至る。
改善措置
全車両、左右のフロントドライブシャフトを点検し、対象の製造ロット品についてはフロントドライブシャフトを良品に交換する。
