Defect

During production of the rear suspension, inadequate control of the application area for the rocker primer — a stone chip protection coating applied to the lower body sides — allows the primer to adhere to the torsion axle mounting surface on the vehicle underbody. This contamination reduces the clamping force of the torsion axle fastening bolts. When driving on rough roads, the bolts may loosen. In the worst case, the bolts may come out entirely, reducing vehicle stability.

Corrective action

On all vehicles, inspect the torsion axle mounting surface on the underbody. If rocker primer adhesion is found, remove the primer and retorque the torsion axle fastening bolts to the specified value. Additionally, inspect the fastening bolts; if damage is found, replace the bolts with new ones and torque to the specified value.

状況

リヤサスペンションにおいて、車体側面下部へ塗布する飛び石傷防止剤(ロッカープライマー)の塗布範囲管理が不適切なため、車体床下のトーションアクスル取付け面にロッカープライマーが付着し、トーションアクスル締結用ボルトの締付け力が不足しているものがある。そのため、悪路走行時に当該ボルトが緩み、最悪の場合、ボルトが外れ走行安定性が低下するおそれがある。

改善措置

全車両、車体床下のトーションアクスル取付け面を点検し、ロッカープライマーの付着が認められる場合は、ロッカープライマーを除去し、トーションアクスル締結用ボルトを規定トルクで締め付ける。 なお、トーションアクスル締結用ボルトを点検し、損傷が認められる場合は、当該ボルトを新品と交換の上、規定トルクで締め付ける。
