400ex stearing stem bearing

[Fenix169motox]

Hey guys, i got a problem with my lemon 400ex, like usual.
there is a bearing at the bottem of the stearing stem that sits in the frame, and its all torn up and today the inside half fell out of it when i was changing my stems.. and im just curious to what size it is and how hard it is to replace or at least get the old one out.. my senior pixx are soon and i kinda need it put together asap so any help is much appreciated, thanks

I don't know what size it is, I would go back with OEM,

As far as removal, it's pretty simple, the stem has to come out, then you remove a snap ring. After that, it should just lift right out.

This link will show you how to remove the stem and the bearing and seals. (it's about half way down the page)
