The hazard
On certain vehicles, the castellated nut and cotter pin on the steer axle may not have been tightened to specification. This could cause the tie rod to become loose in the steer axle, which would result in audible noise and/or looseness in steering. If the vehicle were continued to be operated in this condition, the tie rod could disconnect from the knuckle, resulting in a complete loss of control of a vehicle wheel, which would increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect the torque of the castellated nuts on the tie rod, and replace the tie rod stud and knuckle as necessary.
