Mercury Marquis Steering Column
Q. I have a 1993 Mercury Grand Marquis. I have to take out the steering tube out of the steering column and put the new one in. I am worried that there will be things that will pop up at me and that I will not be able to put it back the way it was. I have no money for garage so I would like to do the job myself.
All I know is that I have tilt steering and cruise control. I don't know is this matters or not. What kind of tools will I need before I start the job so I am not stuck and not be able to go get what I need because the car steering is apart. Basically what I need to know is how to do the job. I have no clue. But I learn fast. I am, I think, very talented.
Thank you, I appreciate this.
