Losi 8T rear end blowout.
Here is the low down...
I converted my 8ight-T to brushless. Everything so far has gone pretty well. After about 4 races, the rear end made a loud clacking/grinding sound. Uh Oh! I pitted. Sure enough, the bearing was toasted (completely separated) on the rear differential. No biggie right? I wanted to replace it with the lightened out drives, and HD differential cup/case anyway. I also wanted to install the Losi aluminum bearing inserts.
After dissembling the back end, everything (other than the toasted bearing) looked to be in good condition. The plastic bearing insert was a little rough, however I was replacing that anyway. Everything else looked ok.
Here is my question...
After reassembly, turning the rear drive shaft feels very 'grindy'. It is as if the rear pinion and ring gear are not meshing well. I took it apart again to reinspect. There is obviously some visible wear, however nothing that looks drastic. The truggy is only 3 months old as it is. Is this always the case? I have never noticed it being rough, but maybe I haven't payed that much attention. If anyone has any insight, it would be greatly appreciated.
