Strage 1g problem. Speedometer?

[fooked]

I was driving my 1g to work this morning, and I was about 4 miles from my house getting on the freeway. Everything was fine, but I noticed this "whirring" sound. I turned down the heater and the radio, and the sound was extremely loud. It was kind of pulsating and I couldn't tell where it was coming from. The car was running fine. No C/E light or anything. I slowed down a bit to 50 or so. I look at my speedo and it's all the way up at 125mph! I had just gotten on the freeway and I'm pretty sure I didn't take the ramp that fast. So I pull over then all of a sudden the speedo pops all the way back down to the correct speed and the noise goes away. Could this be the speed sensor the speedo cable? I wouldn't think that those would make that kind of noise. It was extremely cold out this morning, so I'm not sure that couldn't have caused it.

Any ideas?

Thanks.

Your speedometer drive cable has died.
