Pure speculation, but I wonder if there is a shortage of diff oils even at an industrial level and the assemblers are trying to scrimp on amounts.
I am certain Arrma is aware and working on it, but with COVID-19 they can’t just send people to the factory to get on top of issues like this, so it may take a while. They certainly will have produced a large quantity of trucks for the holiday season and I suspect we will see improvements in QC in future batches.
It’s a good thing the EXBs have limited slip, because I can’t get much for diff oil right now over 50k. I will likely convert my Notorious to EXB diffs this spring anyway, I like the LSD effect so far.
