Question
I'm needing to know how to replace them in detail.

Answer
Ron,

You need to purchase a Chilton's or a Hayne's repair manual for your vehicle.  They can be purchased at most auto parts stores for, around $20.  They have the information you need, along with basic trouble shooting, and repairs, including nut sizes and torque settings.  If any special tools are needed the manuals will list them.  These manuals are designed for a year or range of years for specific vehicles, and are invaluable if you are planning on doing any repairs, or maintenance yourself.
