Well the first time out with my yokomo bmax2 ver3 worlds/factory that I bought used I managed to stripped a few teeth off of the ball diff gear.
I pulled apart the gear box and all looked to be in order, all bearings were good, top shaft and idlers looked good. This just left me totally perplexed to the issue. Well I finally got around to breaking down the ball diff and found the culprit. One of the bearings inside the ball diff totally distroyed and I mean totally. I only had the upper and lower bearing races left. No balls, shields anything but a bunch of silver glitter all inside the diff.
In my 20 years of RC I have never seen a bearing in a diff this destroyed. I am just chalking it up of a one off fluke. I did get the car used from a trusted seller and the car was in amazing shape, just one of those things.
I will run the gear diff until I can get a new ball diff but will most like build it up with Avid Aura bearings and bfast diff kit.
Im also changing the ball cups out to J concepts ball cups Part# 2181.
The car is a amazing car and cant wait to get back on the track.
