I use the cheapest black rubber sealed bearings from Avid. I have been using those for a long time and I get good long life out of them. And I prefer to run bearings with good rubber seals on both sides in an off road bashing truck. IMHO, ceramic bearings with one seal are good for hardcore on road racers, or for someone trying to beat the E-Revo speed record.
Yes the E-Revo is still doing well hanging from the garage wall The snow has arrived up here and I'm pretty much done for the winter. Unlike last year, I won't run my truck in the snow very often. The diff cases of the LST diffs are a tiny bit different each time so the shimming is done accordingly. Either on the ring gear, the pinion or both.
