My key does not spring back after starting the motor. I need to replace the tumbler. I have worked on many older vehicles, a lot. So I think I can do this, I would like to know the steps.
Most often the lack of spring back is not the key and tumbler set itself. There is no spring back in the tumbler but rather the internal area of the column- you can determine this by cylinder removal if you know how to remove. A 96 is most often what they consider a 10 cut side bar ignition. by diconnecting your battery and removing some shroud around the ignition. You will need to turn the key to crank postion and hold it their in order to depress the retainer that holds the cylinder in place, located top ignition.( Retainer small hole area)
While depressing retainer pull cylinder out -and you will have lock in hand for you to examine.
