Doing some fall maintenance; oil and filter, greasing prop shafts and chassis etc. Saw this when I removed front shaft boot:
I'm guessing the drift pin must be flush before snap ring can be moved back into place. I grease shafts every fall and this definitely happened between last year (Nov) and now and I didn't really have that many 4WD hours in that time period.
Here's my buddy Cooper. Every fall he shows up to winter over and make little hawks. When I work my brush pile he stands by in case an "opportunity" arises. I think he cashed in on a couple Carolina anoles today.
