call marlin about it, I had a similar issue and it ended up being a known problem with the bearing manufacturer.
I just finishing re-bearing my case, bought the inchworm kit, to replace the JOKE of the TG kit I first bought.
I re-did the bearings since the failed adapter bearing introduced a bunch of filings into the case and the bearing surfaces were pitted.

Yup, they are sending me out a bearing. I think I caught mine quickly so I shouldn't have to do anything else but replace the bearing and clean up the cases. I saw your bearing pictures and my looked nothing like that. I think mine not being a DD helped since it hasn't seen very many miles on it.
