Hope it all works out! Repeated sensor failures can also indicate other problems that then cause the sensor to fail. For example when my KJ was two years old, I had the sensor that reads from the rear diff crown wheel fail 4 times over the year. I would get an ABS warning light, and the odometer would stop counting.

Jeep replaced the sensor 4 times without trying to find the cause... In the end, I started hearing a harmonic in the back end. When I told Jeep that, they then inspected the rear diff, and ended up replacing it. The prop shaft bearing had collapsed, so the gears in the diff were wobbling, and throwing off metal filings, which were causing the sensors to fail.

Hope you have a simpler solution!
