| Multiple Axle Suspension Torque Arm problems |
On 19 June 2012,, we received information from our ambulance manafacture sales represenative on a safety concern of another ambulance service in the area that reported a failure of the bushings for the torque arms on their 2011 International navastar 4300, which has less than 60,000 miles. Upon receiving this information I immediately took both of our 2011 International navistar 4400 and had them inspected at the International dealership and one of our two 2011 International navistar 4400 was noted that the left rear torque arm bushing had moved out away from the arm and was against the frame of the truck.
