I need to change the gear on the end of my speedo cable to recalibrate for larger rims and tires. Can anyone tell me where the speedo cable is (can it be seen while laying under the truck)? And which gear should I get?

 

What year is your truck? They quit using gears in '98 or '99 and went to electronically controlled speedos.

 

My truck is a 1998 Expedition.

 

You should have a mechanical driven speedo then. I forget the color choices, but Ford uses different colors to classify which speedo gear you'll need. You should call a local Ford parts dept. and ask for advice....speedo gear changes are very common amongst truck owners.

 

1999 was the first year for the electric speedo. 1997 & 1998 used the old-school drum-type odometer.
