Defect Summary
These vehicles have front axles with brake cam operation opposite to the rotation of the brake drum (cam opposite), and there is a tendency for brakes to chatter under low air pressure, resulting in vibrations.

Safety Consequence
Cracks in the tie rod can result in separation of thetie rod and loss of vehicle control without prior warning.
Corrective Action
Replace the cam opposite brake actuation with cam same brake operation, by interchanging the left and right cam assemblies to avoid brake chattering; and replace tie rods.
