The VX is currently at a trusted Isuzu shop and they have given it a complete once over and found no leaks in boots or anything else around any of my wheels.

They did confirm that the pinion seal was bad and the lower oil pan seal was bad.

honestly, I am really thinking it might have been coincidence and it was a stray dog that came over and peed on my rim. Thats the only explanation that makes sense for this "magic bullet" dilema
