Defect
On low-floor twin-steer large trucks, the clamp bolt and nut securing the left tie rod of the front front axle were improperly tightened, reducing the clamping force at the clamp. This allows play to develop at the tie rod end threads, permitting mud, water, and road-salt solution to intrude. Continued use causes the threads at the tie rod end to deteriorate. In the worst case, the tie rod may pull out of the tie rod end, resulting in loss of steering control.
Corrective action
On all vehicles, replace the front front axle tie rod assembly with a non-defective replacement.

状況
低床式２軸の大型トラックのかじ取り装置において、前前軸タイロッド左側のクランプボルト／ナットの締付けトルクが不適切なため、クランプの締付力が低下するものがある。そのため、タイロッドエンド部のねじ部にガタが生じ、泥水や融雪剤などが浸入し、そのままの状態で使用を続けると、タイロッドエンド部のねじ山が損傷して、最悪の場合、タイロッドエンド部からタイロッドが抜けて操舵不能になるおそれがある。
改善措置
全車両、前前軸タイロッド一式を良品と交換する。
