Just finished RC8B3 build. Raced it Sat nite, been racing an 8.2 for the past year, B3 is like nite and day. It is SUPER. During the build I could not get zero end play on both the front and rear diff pinions. Pressed the shaft and pinion with a vise and wood dowels and there is still about .010 end play. Ran about 9 tanks through it and took the rear diff apart and found no metal or wear going on. Just does not seem right to Me having that play. Input?
