Replacing the steering wheel is a simple task if you use a breaker bar and a steel pipe to counteract the force needed to loosen the 10mm Allen screw holding the wheel in place. It is estimated that there is greater than 65ft-lbs holding the steering wheel in place. Without the leverage of a breaker bar and a pipe to counteract the force you will have to use to loosen the screw, you will not be able to loosen it using conventional means.

Before you do any work on your car it is important that you wear safety glasses, work gloves and dispose of all fluids in a safe manner. Coolant is poisonous and should be treated as such. Animals and small children have been known to die from ingesting coolant. If you have to jack up your car, make sure to use jack stands and chock your wheels as well as applying the parking brake. Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you're working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability. Always wear eye and hand protection. Disconnect the battery before working on your car.

Before the steering wheel can be removed, the sheering wheel pad must be removed.
Figure 1

Before the steering wheel can be removed, the sheering wheel pad must be removed. To do this, simply lift the pad off the clips holing it in place.

An alternative method to remove the steering wheel without removing the pad involves the removal of the emblem in the center in order to access the Allen screw.

An alternative method to remove the steering wheel without removing the pad involves the removal of the emblem in the center in order to access the Allen screw. If you do not want to remove the pad, you can loosen the Allen screw, but you will need to have someone hold the steering wheel in place as you attempt to loosen the Allen screw. Removing the emblem is easy and done so by lifting it off with a flathead screwdriver or a plastic trim prying tool. 

Once the pad is liberated from the wheel, simply lift it off the clips.

Once the pad is removed you will have access to the lead for the horn switch.

Once the pad is removed you will have access to the lead for the horn switch. Disconnect the lead from the wheel.

Slide the pipe through the steering wheel as pictured.
Figure 5

Slide the pipe through the steering wheel as pictured. This will help to provide leverage when loosening the Allen screw. Use a 10mm Allen wrench with a six-inch extension on the breaker bar. If you line up the breaker bar with the pipe, simply force the breaker bar down as you pull the pipe up. Using equal force will allow you to loosen the screw without turning the wheel. 

After the screw is removed the steering wheel can then be removed.

After the screw is removed the steering wheel can then be removed. Installation is the reverse of removal.
