The hazard
On certain trucks, the Chalmers 1200 series air-ride suspension may develop cracks in the welded joints between the outrigger spring brackets and the main sawhorse "A" frames. These cracks could grow under normal service to the point that one or both of the outrigger spring brackets could fail.this Could cause the frame rails to drop onto the rear axles causing damage to the tires, wheels and axles. This could result in loss of vehicle control and crash without prior warning. Correction: Sawhorse assembly will be replaced or reinforced as required.
