Outer Limits 4x4 Board

Hi all,

Will be doing a centrebearing on my 89 RN105 shortly and want to make sure I've got the right size impact socket on hand- anyone know what size the nut is??

Thanks in advance

24mm socket and rattle gun made short work of it

Looked like OEM bearing and punch/stake marks, not bad for 360,000kms......I wonder if the replacement will last that long...
