On certain vehicles, the rear differential unit pinion nut may not have been tightened correctly during manufacturing. If the pinion nut loosens, it could cause noise, vibration, reduced gear and bearing life, and a differential fluid leak at the pinion seal. In the worst case, the rear wheels could lock up while the vehicle is in motion, causing a loss of vehicle control, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will check the torque of the rear differential unit pinion nut and, if necessary, replace the rear differential unit.
