It is probably the Vehicle Speed Sensor in the rear axle housing. It is mounted in the center / top of the housing with 2 wires going to it. Takes 5 min. to replace. To be sure if it bad, run the codes on it, the should be one for the VSS.

It isn't an expensive part, but try cleaning it first. Fixed mine.

Mine just started doing this. Was reading 70 then dropped down to 60 then back up to 70. No check engine light showing so I wouldn't think it had codes in it.

Easy to replace. If is isn't the sensor, it will go soon enough if you are doing any kind of driving that isn't on a perfect smooth road (I haven't found such a road in America yet).
