I ran my cat for the first time friday and my front diff kept loosening
. I rebuilt it, retightened it, threadlocked it but it kept coming loose. It happened about 8 times. I finally discovered that the oring seal was grabbing the adjusting screw and gradually loosening it. I removed the seal and the problem was resolved.
It sounds crazy but I noticed this occuring when turning the diff by hand. It doesn't matter how hard you tighted the set screw because the seal would loosen the screw. Weird, but I ran it the rest of the day and the following sunday and no problems.
