Front diff clutch/pinion/acuator

So looking at the front diff I tore apart, initially I thought I could simply clean it out and replace all the bearings and seals, but the front clutch housing that the pinion gear slides down in has a roughness to it when I turn it. Pinion gear is out, and the pinion bearing needs to be replaced. I’m talking about spinning the other end of the clutch. Is there a bearing in there or ???
