which speed sensor?
got a 95 ranger 5spd, 300+ miles on it. i have been through 2 clusters and just replaced the actual trip/odometer gauge on the speedo cluster out of a newer cluster and its still intermitenly working not working. so im thinking it has to be either the abs/speed sensor on the rear diff. or the speed sensor on the tranny. just not sure which one sends the signal for the odometer/trip, which i know reads off the speedo gauge. preciate the help!!!

For 95~97, it's the VSS Signal Generator - 2WD is on the right side of the transmission, 4WD is on the transfer case. The SG is driven and calibrated by small interchangeable gears similar to the way a speedometer cable is driven. So, besides the cluster, there are the gears, the wires and the SG itself to consider.

If the speedometer is working but the odo is not, then I'd say that the fault lies in the speedometer assembly and no where else. The motor in the speedo that moves the needle also drives the odometer via gears that eventually wear out and fail.
I have no explanation as to why replacing the cluster did not fix the problem except that the gears may have also failed in the replacements.

Over what mile interval are you seeing this 3-4 tenths difference? Your speedometer can be off by just a hair. I'm sure your GPS just shows whole number speed, unless you are doing under 10 mph. Since the gauge in your truck is analog you could think your gauge is showing right at 60 mph but it could actually be 59.5 mph. But you would still think your gauge is right on your speedometer. Plus the GPS rounds its speed. This would be the reason for the small difference in the tripmeter.

If the speedometer works, then the VSS Signal Generator, its transmission drive gear and the wires between the SG and the cluster must all be OK. I know that you don't want to hear it but it would seem that the problem must be unrelated to the speedometer.
The way I see it, there's nothing left except the gear drive from the odometer motor or the motor itself.
Replacement worm gears are available from several sources but they are not cheap. I don't know that anyone sells the odometer motor separately.

OK, then how about reinstalling the other cluster with the new odo motor and gears? That should eliminate any electrical problems within the cluster.

the org. cluster i had had no tach...the odo/trip completely quit working...(due to worm gear) installed 01+ cluster but tach and temp gauge were off...same result though on odo/trip...then i installed 95 cluster with tach worked great for awhile then it started doing same thing...so i removed odo/trip with motor...worked good for about an hr then started same thing again...lol
