NHTSA recall 07V470000
Suspension › Front › Control arm
Pierce Custom Chassis
The defect
On certain fire trucks equipped with an independent front suspension, a pitman arm might fracture under severe load caused by three loading conditions. in all cases, the front axle must be turned full left or right while (1) simultaneously backing up and braking hard, (2) driving one wheel over or against a curb or (3) steering the front axle full left or right when the vehicle IS stationary with the service brake applied. these are all low or no -speed events.
The risk
Such a break could lead to the suspension losing one of its anchor points, thereby potentially causing loss of vehicle control without prior warning which could result in a crash.
The remedy
Dealers will replace the original pitman arms with pitman arms made of higher strength material. the recall began on october 29, 2007. owners may contact pierce at 920-832-3000.
