Yd25 doesn't have adjustable tappets. Front wheel bearing repack every 40k km, which is why Nissan charge so much.
There will be other things too, as mentioned above, check the service book and it will tell you. I don't know if they do a full fluids change, but I did my 80k myself and changed everything.
You don't have to take it to Nissan. Better off finding a decent independent mechanic that will probably only charge half that and do a better job.
