output shaft from diffs gets wobbly.

[Nigel]

Well, I know it's bad if the output shafts are wobbly on the differential. But I shimmed them correctly and followed both these posts.

After I finished building the diffs the output shafts were not wobbly at all. But after running two packs throe it, I can wobble them side to side and up and down.

well i ran it again for about 5 mins today and nothing seems to strip but again it was only 5 minutes.

The wobble isn't caused by improper assembly. It's happening because the hole that the outdrive sits in has worn and has more play now compared to when it is new.
I noticed my rear outdrive on the diff case side was wobbling pretty bad, so I replaced the plactic diff case. This help reduce the wobble a lot. But even with brand new parts, there is still some wobble.
I've not had anything break yet because of excessive outdrive wobble, so it might not be anything to worry about.

Nail on the head, this is why the diff casings are so cheap. I must admit they should last a while but if you let them go too much the internal gears will destroy themselves.

I recommend them to be changed once a season just in case.

I've ran mine for about a year and a half with no problems

Dont worry about the wobble. A year and a half with the same outdrives and diff gears without any problems. Knock on wood. . Still running the 2009 (retro) spec.

like i said again i shimmed them perfectly and i have only ran it for about an 1hr and a half in total so i don't think the diff boxes are worn down.

but by the sounds of what you guys are saying i don't think i have to worry about it
