Hey... so I've read literally this entire thread. And sadly I'm only slightly less confused. I get that you have to shim your diffs sometimes, and I understand why. I still don't understand how you know when you need to shim, and what parts of the diff need to be shimmed.
I have a Fireteam and an Outcast 4S V2... I also have a new Traxxas Sledge that I haven't even run yet (please don't judge me; I might just sell it).
The first two have had some use just around where I live. No major air... by that I mean they may have gotten as high as five feet in the air. Landings have been about 50% okay and 50% sketchy or just plain bad. Nothing broken yet. But I'm new to this and just the other day read that I need to be letting off the throttle when they land to avoid driveline damage. Upside is that the ground here is dirt that is pretty soft. These things do a great job of making visible tracks and throwing dirt and gravel everywhere. So that might be a saving grace at this point.
Anyway... at what point should I be pulling these diffs and checking them? I had the front diff out in my Fireteam recently when I thought I had blown it, but it turned out to be user error with regard to the little cups that screw into the knuckle that cover the pillow balls (is that what they're called?) that the knuckles pivot on... one was out too far and causing the wheel to rub a little bit and not turn.
I had opened the diff and everything in it was fine, and had a decent amount of fluid. But at the time I wasn't even aware of this whole "shimming" thing so I didn't think anything else about it and reassembled it.
So... what do I do? Leave it for now? Pull it and check?
