Bearings in the rear hub - replaced and regreased
Bearings in the bottom bracket - replaces and regreased

And some other work not needed to be mentioned here. So tonight, once I get back home from work, I'll take the bike out and go for a spin. Based on all the work that was done on the bike though, I'm optimistic the noise is now gone.

@2manybikes there is approx 10,000km on the rear cassette and there there was over 5,300km on the chain.

@Baboo Next time I have the cassette off (which will likely be when I replace it next) I'll look for the spacer.
