I noticed in the long term, bearing wear/play in the diffs becomes a factor also, at least with the stock bearings anyway. Also recently, I replaced a diff that had an issue with one that didn't and retained the ring gear. I didn't notice any play but It Started stripping on the second run. I replaced the gears and it's fine now, but I'm wondering now if I should have tried another shim first. Gears aren't cheap, but the wear is hard to gauge.
I went through a few crown gears on this platform before I discovered what diff shims were but that was back in the day when Arrma didn’t send them in the box with a new truck. I usually go 1 or 2 full runs before I install the second shim. After I learned this I’ve never had any more problems with stripping diffs on this platform. I think with any hobby some things come naturally and some things you just have to learn the hard way. Hopefully your video will enlighten people before they go through what I did when I first started lmao.
I came across this video because I’m new to the hobby and I don’t know anything about it (hence the RU-vid search for info on the diffs) great info in the video, and at the great risk of sounding like a snowflake may be try being a little less condescending
