I saw silly putty and even silicone earplugs mentioned elsewhere but couldn't tell if it was a joke or a viable alternative.
I dont like the silicone ear plugs because there will be some movement of internals but won't be symmetrical. The putty is not bad but will also eventually lead to movement of diff.
I recommend either:
1. 1 million silicon oil.. this will give you some diff action
2. Epoxy the gears and turn it into a spool
