FREIGHTLINER CL112/120, CST 120
What the hazard is
Mechanical failure
What to do
Make arrangements with any authorised Freightliner dealership to have a retaining collar fitted free of charge to prevent the shaft from moving in the splines.
Defect
Due to incorrect machining the splined end of the ZF steering shaft could push through the lower yoke. If this were to occur it could lead to a loss of steering control.
