Rear Main Seal And Clutch 1990 Y60

Hi All

I have a major Rear main seal leak.
Ordering a kit off patrolapart.
Watched a few videos on how to do it and have a rough idea, What im looking for is suggestions on what else to fix whilst i have the trans out.
im planning on doing diffs and swivel hubs all bearings and seals.
Already replaced slave and master cylinders. and a few small things

im going to order Bearing puller online Both outer and inner bearing kits.

Thanks in advance, any suggestions are appreciated
