And here's the chassis, you can see there is diff oil that leaked out, confirming my suspision that the diff hs been leaking.

I'm thinking about cleaning my tranny gears once I get the new parts in, just to make sure the red and tacky gets good adhesion to the gears and doesn't fling off.

One of them, stIll need to figure out why it's locking and unlocking, I'm guessing that's caused by my spider gears having play

there wasnt any grit or anything when you tore down? all the bearings are rolling free and smooth? is the diff housing at all warped? those would be the only reasons i could think of, maybe the spider gears sliding back and forth on the square inserts, but i would think that if everything was in there as it should it would force them to be at the outermost location making them if anything always be loose/open. unless there was enough play it could start getting sideways and wedge.
im way to used to seeing the spiders being on shafts across the diffs lol throws me off seeing them in the inserts like that separated.

No everything is fine, I think the inserts are the problem.

Thanks man! Appreciate it. On the diff, instead of doing a rebuild kit, I think I'm going to go for one of those madmax (bassically rovan) billet (I think) diff cases with new bearings, seals, hardware and shims for not too much more, now I'd much rather go for a turtle racing or irc becuase they are stronger and nicer but for now, that will have to do, tell me what you think.

Also think you gonna do the diff twice in the end anyway? hope the diff holds out??

So your saying do the mad Max? The diff most likely won't be a problem unless it leaks, but then again I've seen people smash these SS style cast cases. John Parks says it all be fine though, the tranny gears and diff case is the problem
