Ok so with a new complete diff and input gear I put it back in the yoke and make sure it's spinning freely and and snugged up. I paid it down onto the chassis double check to make sure everything is free spinning and it feels like it's catching and rubbing on the chassis but I cannot see any marks to show that. Any ideas? It's almost like when they yoke has any pressure on it like it's sitting down and its own grooves make it too tight on everything
