Worth changing both speed sensors?

I've got a 2012 Deere 700K showing speed sensor faults intermittently. I swapped the sensors side to side and the issue jumped, then settled on the other side after track testing. Machine has 4800 hrs. Would you change both now or test voltage first?

Since the fault followed the sensor, it's likely that one's on its way out. Testing voltage with a multimeter could confirm it, but with 4800 hrs, swapping both might save future downtime. Did you notice any wiring wear or connector corrosion while you were in there?

The new sensors arrived on Tuesday and I put them in that afternoon. Ran the dozer hard all day yesterday and the fault is gone. Changing both was the correct move.
