Western Star Conventional: Steering

Affects Western Star Conventional · 1994 — about 396 vehicles.

The hazard

On certain trucks, the steering knuckle (where the steering arm is installed) may not have had corrosion inhibiting grease removed prior to assembly. The joints may also have been assembled with keys and nuts that were softer than specified. This may allow the arm to turn inside the knuckle thus shearing the locator key. If the arm is allowed to turn freely, steering control will be lost without prior warning and a crash could occur. Correction: Steer arm/knuckle joints will be cleaned, nuts and keys will be replaced and nuts will be torqued to specification.
