fluctuating speedometer in 95 f-150
First off, I just wanted to say thanks to everybody who contributed possible solutions to my previous posted problem. I have changed axle ratios in my 95 f-150 4x4 from 3.31 to 1 to 4.10 to 1. When I bought the truck, it had 33" tires on it which I have kept. Now my speedometer is fluctuating back and forth while driving. I'm assuming the speed sensor is reading incorrect data from the rear axle. Any other ideas? Thanks.

I was told that the sensor in the rear did control some speedo function, but I am not sure about that now, as I did replace the sensor, which cured the ABS light problem for a few days, but it came back. I was told by the mechanic that did the job, that the speedo gear was worn, and metal was flaking off of it, which would cause the ABS sensor to act up.

Lallen, I just got my truck off the rack from my buddy's shop and we found the problem to the "jumpy" speedo. When 4 wheel performance centers swapped my diff and gears, they damaged the "tone" ring which bolts to the diff carrier. The rear sensor detects each of these "teeth" on the tone ring to determine speed and anti lock braking info. Mine had 4 teeth chipped of mushroomed causing the problem. Hope this helps.
