Mike used to have a diff for this transmission which had a steel gear screwed onto an aluminum case. I don't think he makes them anymore ($12 for an assembled VXL diff puts his $60 diff out of business) but if he re-made them but sealed them up I'd be interested in one. Not sure if I want to spend $60 on a diff, but it would be nice to get something that keeps the diff grease in there.
I ran automotive wheel bearing grease in my ER's diff for a long time and I liked the feel of it, but it eventually broke down and leaked out. I switched to white lithium grease and I really like how the diff feels when it's freshly packed but after just an hour or two it has already loosened up and started leaking. I hate pulling my diff out all the time, so I just leave it loose and deal with the terrible unloading. I'm thinking of trying some non-sling, high temp Moly grease next time I have the diff out, hopefully that'll stay in there a litle longer
