I wasn't brave enough to have a go at the rear hub since i've got no idea how to get the cluster off.

To get the cluster off takes the right tools. Freewheel or freehub?
Hope this helps.
Of course you could search Sheldon Brown or Park tools for tips too.

I put a good layer of grease into the cup. Feed in the balls. Put a layer on the cone, then screw it all together. The excess gets cleaned up as you.
You'll see all sorts of stories about limiting the amount of grease because of friction, etc, and it's true, a racing mechanic will use very little grease, but he's planning to rebuild the hubs after every day's racing. You're not.
Hubs are a very simple device and as such, don't need too much over thinking. If they're gritty, the cones are too tight, if the axle wobbles, the cones are too loose. That's as complicated as it gets. Getting the cone adjustment right is a bit of black art but if you're willing to redo them if they don't feel right, there's nothing scary there.
Quite frankly, adjusting cone and cup bearings is one of the simple pleasures in cycle mechanics.

Doing hubs is almost Neanderthal. The cones simply unscrew with simple tools. For cleaning I use an old rag, some $2 degreaser & plenty of water pressure to hose them down. [no drought or water restrictions here] Sometimes an old childrens toothbrush helps loosen the stuff inside.
I just stick my finger in the grease & drag out a 'dollop' & stick it in, then smear it all around.
In go the balls, one by one, followed by a another, but smaller smaller 'dollop' of grease. Axle & cones get a smear & in it goes.
Adjusting the cones to that precision point of perfection is fiddly, but so rewarding when you get it perfect.
Any surplus grease that makes its way outside is easy fixed with another clean bit of rag.
Rear hubs usually require a freewheel remover, but I have all the right tools anyway, so it's just a doddle & sooooo satisfying.
Now that's AUSTRALIAN to the core.
