Rear Suspension on 2003 GMC Envoy

The rear air suspension on my car seems to be failing. What is the most likely cause; pump, shocks or air bags and what would the cost be to fix it? Thanks much.

It is not uncommon for the rear air suspension air pump to fail on your GMC Envoy. That being said, the system should be completely diagnosed buy a qualified technician before any parts are replaced. Most of the parts for the air suspension system are quite expensive. Proper diagnoses of this system is critical to avoid replacing parts that do not correct the problem.
