Hazard
On chemical fire trucks with dual rear-axle drive, the spring slip-stop geometry on the rear-front and rear-rear axles is inadequate. During sharp turning maneuvers, the springs may disengage from the slip-stops. Continued operation in this condition can result in springs failing to return to standard position, causing vehicle tilt and potentially compromised steering performance.

後２軸駆動の化学消防車において、後前軸、後後軸のばねズレ止めの形状が不適切なため、急旋回を行った場合、ばねが当該ズレ止めから外れるものがある。そのため、そのまま使用を続けると、ばねが標準位置に戻らず車両が傾き、最悪の場合、舵取り性能が損なわれるおそれがある。
Remedy
Add extension plates to the upper portion of the spring slip-stops on both rear-front and rear-rear axles for all vehicles.
