Safety Recall –
Peterbilt is seeing failures on the Model 320 and Model 520 tracking rod brackets with Hendrickson HAULMAAX/EX suspensions in refuse operations. The tracking rod brackets may become detached from the axle. If this happens the axle loses its primary lateral stability, which may increase the risk of a crash. There is no warning preceding the failure of these components.
