With the onset of Winter and the cold weather we found that the speedometer does not work properly.
It reads about 20mph low until we drive about 20-40 miles. I can tell when it starts working as it jerks or jumps up a couple mph closer to our actual speed. Once it starts working properly its good for the rest of the day.
Unfortunately the majority of our driving is 8-10 miles.

It's as if the grease in the cable is freezing...is there someplace I should lube the cable?

Thanks all...
