Shortly before reaching Yellowstone National Park, the ABS malfunction occurred for the first time. However, it disappeared automatically after a short distance. After that, the fault occurred more and more frequently at regular intervals, but disappeared again after a short distance. We were never able to read out the fault data in a targeted manner, as the fault disappeared immediately when the diagnostic device was connected.
On the date mentioned above, we had the first opportunity to read out the current fault and diagnose the fault codes from the left rear wheel (C1020 + C1027). Unfortunately, the codes didn’t tell me (Tom) much, but I suspected some kind of faulty contact in the supply line.
I didn’t find a bad connection, but I removed the ABS sensor on the left rear wheel and was a bit surprised about the grinding marks on the sensor, sensor wheel side. The sensor wheel also showed slight signs of wear on certain tooth flanks. The wheel bearing play on the rear wheel was in the normal range according to my assessment, i.e. no excessive bearing play.
When reassembling, I made sure that there was more clearance between the sensor wheel and the sensor.
Exactly 865Km there was no malfunction of the ABS and everything worked properly. Then, while reversing off-road, the ABS malfunction occurred again on the rear wheel.
Again I examined the left rear wheel and was surprised at the slight wheel bearing play. Was this the cause of the ABS malfunction, i.e. the wheel bearing play was touching the sensor? I guess we have to pay more attention to our wheel bearings and replace the bearing as soon as possible. 🙁

Starter battery failure
Since the last days the starter battery announced its end of life. In the morning, the engine could only be started with the help of the auxiliary battery or the on-board battery. Now it was finally over; even for the warm engine, the starter would no longer engage and do its job. The starter battery definitely had no more juice!
In Kamiah /ID we got a suitable battery at NAPA, as we know there are no spare parts for our diesel jeep in North America, and after successful installation in the car park, everything worked again as desired.

Oil and universal joint change front axle
Our Jeep was due for several service jobs. For these we went to an official dealer. Unfortunately only the engine oil could be changed. For all other work like changing the oil in the differential gears and for reduction gears we should have booked an appointment in advance. The change of the engine oil was necessary, the other transmission fluids should, according to the maintenance book and normal driving, still do their job until the next inspection date. Read More
