Front Suspension Lower Ball Joint problems of the 2004 GMC Envoy

My 2004 GMC Envoy slid into a curb and rolled on its side. I believe that the accident was caused by ball joint failure. I could not get any assistance in the investigation, but I know that the accident was caused by mechanical failure and have pictures and witnesses for this accident. The vehicle was totaled as a result of this accident. This vehicle was purchased new and never had any repairs or work done on the drivers side front wheel. It was a 2004 model with around 20000 miles. I would any information that you can provide and would also like to go on the record with this complaint against gmac. I would hope to keep someone from losing their life due to this mechanical problem. The loss due to this accident was over 30,000 dollars.
