Does anyone know why the C Clip keeps coming off my outcast 8s , I'm ordering a new one as properly stretched but just thought anyone got any advice as to why and if I need to order other bits . This is the 2nd time , this time I stopped the truck as not to damage it anymore as last time the pin that goes through the drive shaft mushroomed and couldn't get the bearing back in . I order CVD Rebuild set of pins and replaced the pin , put C Clip back on but after 2mins of running heard strange grinding sound , stopped truck , tool shell off and noticed the bearing had come out again and the C clip was off the input gear . Very frustrating ...
