The most critical bearings to replace with ceramic if you do nothing else?
May not even be needed; I'm keeping Summit stock for now, I might go Dewalt 14.4 in future, but not brushless or LiPo.
My rear diff bearing- inside- touching behind the pinion exploded. Impressive. I'm in the middle of a teardown, but I have enough new Traxxas "blue" bearings for tranny/diffs already.
But the topic: If you were to replace some bearings at $8 a pop for Acer ceramic, how many would you use, minimum, saving $$$, but still hitting all the biggest "stress-points".
Example: I can replace both outside AND inside 6X12X4 pinion shaft bearings on both Diffs. That's four bearings, $32.
Also could replace tranny bearing on either side of both 20T idler gear #3996X AND idler gear 13T #3976. That's another four bearings, this time 5X11X4.
Total: $64. The 64 dollar question is: can I skimp on not doing say the outside diff bearings or not do the front diff just the rear, etc. Do I really need to replace bearings on both sides of both idler gears...or maybe even leave tranny alone.
Maybe just use up the steel I already have...
