These vehicles may exhibit a condition whereby the rear cradle bolts pull through the retainers due to corrosion of the retainer. If both bolts pull through,
the rear cradle would no longer be supported at these mounting locations and the intermediate steering shaft may separate from the steering gear. If this
were to occur while the vehicle was in motion, a vehicle crash could result without prior warning.
To correct this condition, dealers will replace the rear cradle bolts and retainers.
