M35A3 steering problems

[firestomper]

The fire company i belong to has a M35A3 that was used in Super Storm Sandy for fir fighting and rescues since the storm we have had problems with the steering.

here is my problem when the air asst is on the the truck is all over the road and when you turn the wheel side to side you can feel a bump in the steering. when the the air asst is turned off the truck is not all over the road and there is no bump from side to side in the steering.

Not sure where to start to look for the problem any help would be great.

Have you checked to see if the front wheel drive is engaged? That can cause issues with steering on hard roads.
