Quick answer

Reference Hendrickson Recall 23E-095 Hendrickson alerted Peterbilt to a limited number of Hendrickson COMPOSILITE EXS20 steerable, auxiliary lift axle suspension assemblies and individual steering knuckle assembly components that are equipped with bearing journals that may not have been seated correctly to the backbones of the left and right-side steering knuckle assembly components during manufacture. Loss of oil from the respective axle hubs may cause the spindles to become loose from the steering knuckle assemblies or otherwise fracture and/or cause wheel end hub damage . This can further result in foreign object debris on the roadway, increasing the risk of a crash and/or injury.

What this bulletin may mean before buying

Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
