If your car is not equipped with an air bag, in the steering wheel,  you can in most cases, replace the old steering wheel with a new one.

Before you remove your old wheel, point the front wheels straight ahead so you'll be able to properly install the new wheel. Then remove any center trim or padding that may incorporate the horn button. This usually requires that you remove screws from the back of the wheel's spokes. Pry off the padding. As you lift the pad, check to see if the horn button is an integral part of the assembly. If it is, pull the horn wire from the back of the pad.

Firmly hold the wheel from turning as you loosen the nut. With the nut off, you'll see two threaded holes in the wheel's center hub. Thread two long bolts through a steering wheel puller into these holes. Thread the center bolt of the wheel puller down against the top of the steering column, making sure you don't turn the wheel in the process. Use the puller to pop the wheel off the column.

Bolt the new wheel to its adapter hub. Thread the wire for the horn button or horn ring through its hole in the hub. Align the splines of the adapter hub with those of the steering column shaft, while positioning the wheel for straight ahead. Push the wheel down on the steering shaft. Install the mounting nut and tighten it until the hub seats. Snug up the nut. Attach the horn wire to the new wheel's horn button, and install any trim.
