Rear axle oil seal replacement

[SwampyPom]

Hi, I need to change the rear axle oil seal in my 2012 D22 YD25.
Anyone got any good tips for removing and re-installing the lock nut?
It's a weird shape and needs to be torqued up to a high Nm so was wondering if anyone had done it before and had some pointers..
Cheers.

Assuming all d22's are the same, not sure you have to do that to change the oil seal. If you're going to check/change bearings and so on while you're at it, the below might help. It's a different model but same thing. Can do it without a bearing press, not easy getting it apart though (getting it back on is easy enough). Not sure where you would get a tool to torque the nut (fleabay? make something yourself?), but most people would do it the old fashioned way as per below.
