My 2002 GMC Envoy speedometer started registering double the actual speed last night. I called the dealership's service department and they said that they usually just replace the entire speedometer assembly, but didn't say what caused the failure. It will take several days to get it back, so I will try to update you once I get it back and hopefully a more detailed explanation. Wouldn't you know it, the speedometer was working perfectly on the way to the dealership. I went on anyway and discussed the options with them. Since it's electronic, the computer chip reset when the ignition was started, so it may never happen again or may again in several years, etc. Any case, the assembly would cost around $600, so I opted to wait until a hard failure before spending my money. Sorry, but this doesn't help your situation.
