Will check that out, thanks sparky Paul Also looking at above diagram, I don't have part no 7, and the nut on top of bearing, that goes on directly to bearing then mount sits on top of this right? Mine last time I opened was bearing then nut then mount then top cup then nut. Should the nut that holds bearing down have thread lock on there? I've bought new top cup and top nut and bearing nut from tps and it's not a (blue plastic thing inside nut). One nuts got a lip on bottom and one standard nut. On refitting I plan on filling cup with grease then using something like a Pringles can lid and sealing cups. Regards Tiff
