[sparkywilliam...]

Best way of cleaning out the old grease and any other rubbish in there before new Moly goes in?
Do i just wipe it out with a dry rag or can i use parrafin,degreaser?

Thanks All

The problem with cleaning them with chemicals is that you have to be REALLY REALLY sure you've regreased them well otherwise you could actually be making the problem worse. The absolute best thing you can do is to merely replace them.

Personally, I'd never clean bearings. I'd only ever just re-grease them or replace them. If you clean them you could be creating a problem for yourself further down the line when the one small area you missed with the grease wears out and the bearing fails.

If it were me, and I wanted to do the job properly, I'd just replace the bearings.

Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another.

I don't thing that's an issue - the grease will be spread about all the contact surfaces when the bearing starts turning.
