If it’s anything like mine, I’d clean and regrease the outer bearings plus the caged bearings on the driver assembly. I have have had a lot of water ingress (even more so after last nights soggy commute across London!), all the grease from the bearings had been washed off and coated everything else.
Which leads me back to my problem of slipping gears, especially in first or second gear. The pawl springs on the driver were fine, but the engagement areas on the ring gear were covered in grease and muck. Cleaned it all up as much I could (I didn’t want to get involved in taking the whole thing apart), and regreased bearings etc.
I had only one gear slip yesterday, had been getting upwards of six/seven. It is better, but after watching a bloke completely dismantle and rebuild an old SA hub in about 8 minutes I’m wondering just how hard it can be to open right up? I can see that there are pawls on the planet cage assembly, could this be the potential issue? When it slips there’s a pretty chunky ‘bang’ sound when it re-engages, I don’t think it’s a sound affiliated to the smaller pawls of the driver. Plus, these tick and sing beautifully now after cleaning them up.

Done a bit of research; I think the cones need tightening.
