2 years ago I started leaking diff fluid through the ADC wire cavity that runs in the input shaft plate to the ADC Coil. At the time I didn’t know how easy it was to get to all this so I paid my local dealer $80 to fix it. Well, it started leaking again. And leaking quite a bit. I pulled the input shaft cover/ADC Coil off myself today. What a terrible design. For one, I can’t get to the backside to seal from there which would be most effective. For two, why in the world didn’t they design the wires to go in the TOP of the plate where oil would be less likely to run out? Anyway… All I can see to do is pull the little wire boot out from the front, seal it real good with some trusty ultra grey, press the boot back in and then coat the outside surface up real good.

Does anyone else have any better suggestions or ideas to fix this? The output shaft seal isn’t leaking, just the wire cavity.
