The hazard
On certain trucks, the fifth wheel hitch assembly's lever arm may have been incorrectly installed during the manufacturing process. The lever arm pivot bolt may have been over-tightened which could distort the pivot bolt spacer sleeve and prevent the fifth wheel latch jaw from closing and latching securely around the trailer king pin. This could allow the towed unit to separate from the towing vehicle while underway, potentially causing a crash with injury or death. Correction: Dealers will replace the pivot bolt and sleeve with a hex head shoulder bolt and washer.
