Pas pump query

Hi all

I took the serp belt off other day to look for a noisey bearing somewhere which I think is the alternator fitted on Christmas Eve. Anyway I noticed there’s a bit of play in the pas pump which I’m wondering about but also when I turn it anti-clockwise which is the way it turns when running there is a kind of clicking/popping noise that sounds a bit like a cheap ratchet but not that noisey, there is about 10 clicks per rotation, also some days the steering is poor on tick over

It’s a 98’ 300 d1

So what do you lot think then

Thanks in advance
