1984 Rolls Royce Silver Spur Repair Question
What has happened when my steering wheel system did not respond while driving and the wheel could be spinned 360 degrees?
Our reference doesn't show your vehicle, so I have no manufacturer information to go on. What you're describing is a drive-by-wire system that has completely died or something between the steering wheel and the steering gear broke. Since I can't look your vehicle up, I can't verify if a vehicle that old was equipped with mechanical steering or an electronic steering system.
Open the bonnet and see if there is a column poking through the wall between passenger and engine compartments. If so, see if it moves when the steering wheel is turned. Follow it to the steering gear, looking for broken parts.
