NHTSA recall 94V150000
Structure › Frame and members
Wayne Lifestar
The defect
The stud welds on the frame can fail, causing the "p" clamps holding the air brake supply lines to disengage from the frame. The air brake supply lines can come to rest on the exhaust system, damaging the lines resulting in a leak to the system, loss of air pressure, and engagement of the spring brakes.
The risk
Consequence of defect: application of the spring brakes without prior warning can result in loss of vehicle control and an accident.
The remedy
Dealers will install a "p" clamp retaining the air line to the frame.
