Thought I might contribute something for a change, however low value it may be.

The ABS on my D110 has acted up since I installet MDE lockers and AEU2522's. In doing so, you reset the depth of the ABS sensors, and we have been fiddling with shims distancing the sensors from the ABS ring. I have changed the mounting grease, thinking the sensor may need a ground. I have checked and rechecked tire pressure, and I have pushed the sensor back in by hand a zillion times, thinking vibrations caused them to back out. The ABS has worked for periods, and I have thought many times that I have solved the issues.

This time I seem to have gotten it right, and the remedy is as cheap as it is simple to install. Soft steel wire. Used to tie down the sensors in their "in" position in the swivels. It has worked flawlessly for several days, and I am starting to think I have really solved it now. My theory is that oil pressure between the ABS ring and sensor forces the sensor to back out, rather than vibrations. Meaning that this probably only applies when you run oil in the svivels. And may explain why LR delivers modern ABS trucks with greased svivels and bearings.

Sounds like your CV is moving around in the swivel ball. Or the swivel preload is damaged or set up wrong. The wire is acting like a rubber band springing the sensor back and forth.

Good luck

Pendy, don't try to kill the first theory that actually works. :flipoff2:

When you do the AEU2522 w MDE ABS rings mod, you grind a little inside the svivel ball and move the sensor up a bit for the larger diameter CV, Hence the shims. It is not really part of the king pin setup. I still believe in the oil pressure. It is basically a bearing now, and those can carry much more force than it takes to push the sensor out.

I guess that I should add that there are no contact marks on the sensors.

Early RRC's ran ABS with oil in the swivel. Is your exciter ring larger in diameter, such that it is close to the inner diameter of the large part of the housing? I just have a hard time with the oil pressure theory idea.

Maybe you should run them dry for a day to check out your theory :D

Yes, the CV is bigger, that is the point of the mod. :D

Maybe new mounting bushes, the ones in slotted copper tubing, would also do the job, but I don't have any.
