K13 Front Wheel Bearing

Hello everyone!

I got bearing analysis topic for my final project in college. I know the load distribution and the other information from internet but I can't find the specification of the bearings that K13 used.

So, does anyone know the specification of K13 front wheel bearing? Maybe the rear wheel bearing too.. more information are good to my analysis...

Thanks you very much
not sure if there is one, but possibly a K13 haynes manual.... failing that, a nissan dealer/parts dept. may be of some use.
