Thanks mate it was accutaly an broken axle bearing that had jammed it up.
s-series are the gay shit to lock, mine only lasted 5 corners and i totally welded the top removable spider gear to the crown wheel. And all the welds have to be grinded up flush or the casing bracket wont sit back flat. Hardest centre to weld up ever.
Everyone at the workshop it 100% baffled at how it could of broken it was the cleanest job, Will pull it back apart on Monday an give a full diagnoses. I also have another s-series centre so will be learning from our mistakes an ill post the best way to lock it up.
