Yes that's the meter I'm talking about. My odometer failed at 110,000 miles exactly and it is also making a faint ticking sound from the dash at that time. I think it's coming from the spinning cable feeding the worm gear for the odometer. After about 100 miles of driving the noise went away. My guess is that one of the gear teeth is stripped and the gear struggled to turn. Eventually a catastrophic failure caused it to disengage from the driving cable permanently and the sound went away.

About 2 years ago I also started a similiar thread regarding this ticking noise. It has much detailed information including some pictures, but I can't find that thread. Can someone dig up that URL?
