If your power steering is not responsive, first check the power steering fluid reservoir and make sure there is enough in it. If that does not work, you may need a new power steering pump. Call and let us know the make and model.
If you have dented your wheel, you will need to replace it, and a new wheel is expensive. We salvage usable wheels from out-of-service vehicles, and probably have what you need in stock. Give us a call 215-492-0600
