Odometer stopped working on 98' FLD120

try and get under the truck and look for the cable. when found, remove it, try spinning the gear, if one is still on the cable end.

on another note, maybe it became disconnected at the dashboard? try removing the dash cluster and check if it is still connected to the speedo head.

cable are known to break, and since you truck is so old, that's what could have happened, IF the plastic gear did not explode first.

 

That truck is electronic. Also if the speedo works but odometer doesn't a new speedo is the only fix. Usually a sticker is put in door jam replaced at x mile's.

 

Just make a record of the old odometer reading and the new one. For the miles in between when it wasn't functioning do the best you can using google maps or with an atlas.

As for your concern about buying an older truck, that's why you always pull the ecm records. The ecm keeps track of mileage also. But it can also be changed, so that's no guarantee.

 

When I bought my 2000 fl it had quit counting the distance also. It quit at 1,864,xxx. (Km) I think it quit because it sat for a year or 2 before I bought it. The solution was a new speedo unit.

 

A working odometer is not a DOT requirement, as long as your speedo is working you are good to go legally.

You may also use a mileage program for figuring your IFTA mileage. These items would save you a few bucks from having to replace the speedo unit.

You may also want to consider bolting a hub meter on one of your drive axles, this would give you exact mileage if you prefer, I think they are much less than $315.

 

While it's not needed and you could get a hubometer, if a guy can't spend 300 bucks to fix his odometer just for convenience, he is part of the problem out here with freight rates.

300 doesn't even qualify as pocket change when dealing with trucks.
