I just saw that these are available for purchase at DDM. I had only ever seen the DarkSoul versions that appear to be no longer in production. Anyone running these? I got one to try for the center diff. Thoughts?

Well, I saw that these a being used by a number of folks on another forum, and they only had good things to say about these. Mine just arrived! I was only able to get two, but will get the third when DDM restocks.
 
@Grinspoon,

The reviews I've seen of these have bee positive.

Post your review and pictures once you get them installed. :D

Will do! Getting the completed brushless 5ive running this week as soon as the new LiPo packs arrive and then I'll be putting these in the build i'm working on. I'll keep you updated. I guess the bearing needs to be press fit into place, so I'll need a press and extractor.

No put diff in freezer for a day and put bearings in a hot plate don't melt them put get them worm and they will drop on

Man, you must have a freezer that reaches absolute zero! I tried with my meat freezer in the garage, and with the freezer in the house. I gently heated the bearing in a pretty warm pan... didn't get them too hot. Tried to drop the bearing on and nothing. It was just as stuck as when everything was room temp, that that is stuck! Next I broke out the old text books and a mallet to try to bang it on. That worked to get it on the shaft, but then I was unable to seat it. Finally I found my old vice and a couple pieces of wood and used that to seat the bearing all the way down. I used the diff tower on one side of the vice and the housing on the other side to press fit the bearing into place. Once I accomplished that, everything else fit like a glove. I only did the center diff last evening. I'll be tackling the front and rear very soon. I'll get some photos up here in a second.

Well you got it on might try a soldering iron on the race of bearing for heat
Remember the build is part of the fun [emoji27][emoji56][emoji48]
 
The weight of the entire assembled center differential with all the parts listed is 884.81g.

This is the first time I've ever built a truck from the ground up. I do enjoy the build, especially because this is my first ever. I've never actually even opened a differential prior to this! Two more to go!

I think that backwards. whenever I replace bearings I freeze them and heat part or leave it at room temp. I do this whether I replace bearings in a Zenoah or in a rotor spindle bearings on a real helicopter. Unless your putting the inner race on a shaft than I would say the opposite

I think this is a case of the latter, not trying to seat a bearing in a cup, but on the shaft of the Diff Housing. The inner face of the bearing is making contact, not the outer. So, the idea is if you freeze tie housing, it will shrink ever so slightly and heating the bearing causes it to expand. I should probably try with the front and rear even if I have to press them on. Probably will reduce risk of damaging the bearing.

my question is, how much of a pain in the ass will it be to remove the bearing ?

If you have the right tool, it should be no problem at all. You'll never get it off with your hands though. It is:
