The splined steering shaft may not be sufficiently engaged as designed due to inaccurate drilling of the holes in the frame to which the cab front mount member is bolted. Under certain conditions the steering shaft may disengage. Consequence of defect: a jarring impact might cause disengament of the splined shaft resulting in loss of steering control and possibly an accident.
Replace shafts which measure under the minimum engagement dimensions with longer shaft.
