PACCAR issued a recall on multiple vehicle models

On certain vehicles, the locking tab that locks the outer spindle nut onto the spindle was not engaged or properly bent over. Failure to properly engage the locking feature into the nut may cause the nut to loosen which will eventually cause the wheel bearing to over heat and fail if undetected. If the loose nut is not detected, the outer end (tire, wheel and hub assembly) could become separated from the vehicle. Correction: Dealer will inspect the hubs to determine if the locking tabs are properly bent.
