NAVISTAR issued a recall on the PROSTAR model

On certain vehicles, the rubber isolator material that holds the driveline center bearing in the mounting bracket may deteriorate, which could result in driveline separation without warning. The resultant loss of propulsion, in conjunction with traffic and road conditions, and driver's reactions, could increase the risk of a crash causing property damage and/or personal injury. Correction: Dealers will replace the center bearing and its mounting hardware.
