Affects Western Star Conventional · 1990–1994 — about 98 vehicles.

The hazard

On certain trucks, the timing link ball stud may not be correctly seated in the slave gear pitman arm taper. This could allow the ball stud to turn in the pitman arm taper causing the ball stud nut to loosen and eventually fall off. If this happens the timing link could separate from the pitman arm resulting in erratic or lost steering control with the potential for a crash. Correction: Timing link ball stud will be replaced.
