Well it's definitely not slipper pads but can't work out if it's still circlips as continue to tighten diff after breaking in...it then pings out n looses all drive I'm using carbide balls aswell...really getting frustrated as spent 8 hours now trying to sort this out it's making me think there's a problem with the output cup the circlip sits in as I've changed everything now

really think this is a poor design as never had problems with ball diffs before
