europa The white O ring plays no part in the creaking noise, it’s simply a seal against leaks (it’s a hard PTFE seal). The part that needs lubricating is the O ring here…if it’s split, the ball of the wand may be rubbing against the metal of the nut. Check it and see if it’s OK. The spring will sit on a metal cup (which itself sits on the ball of the wand) with a large hole in it and that needs to be lubricated as well
The O ring actually looks out of place…which won’t help
