The short version

PACCAR Incorporated reported a problem with the power train axle assembly. Here is what owners need to know.

WHAT

The axles may have lower rear pivot bolts that are not long enough to sufficiently engage the locking feature of the corresponding nuts.

WHY IT MATTERS

The short screws can cause the hardware to separate from the suspension system and become road hazards, increasing the risk of a crash and/or injury.

WHAT TO DO

PACCAR will notify owners, and dealers will inspect suspect chassis and replace the pivot bolts, as necessary, free of charge.
