The amount of grease that poured out really surprised me, was semi liquid. I only had standard CV moly grease to put back in, I could not get any of the thinned stuff in time. I did not think about alignment of tripod in cup until I'd pulled it to bits despite having looked out some tippex to mark it with so probably not as it came out!
Maybe should have put in the new tripod but the old one had no more movement that the new one and I wasn't liking the plastic caps at all. If it needs replacing in future I'll do it with genuine part.
Cheers
