Swing arm bearing checking & replacement

After a day out at the local mx track the other day - noticed the tell tale clunk of a dodgy bearing when I pulled the back wheel over from the top. I've only just done the wheel bearings so it's probably not them...
It's not a big clunk but there nevertheless. Can't really see where the movement is coming from but can see a very small amount of movement in the swing arm bearing area.

FE 501 2002 - guess the bearings have not been doen before. Before I strip it all down, whats the best way to check it is the swing arm bearings and not something else, and assuming it is - any great tips on how to go about the replacement job...have looked at an old thread here which talks about heating the swing arm & putting the new bearings in the fridge before pressing in.

Reckon I'll have a go myself with limited tools - seems like a bit#h of a job.

So - looks like I'm going for it.

Took both nuts off spindle & finally managed to knock it out & remove the swing arm (at one point thought it would never come out but kept smashing it from boths sides alternatively with a decent drift plus the nuts on obviously to protect the threads). Had to take the brake pedal off - then plunger dropped out - not sure if thats normal but will deal with that on reassembly.

So any tips....what about the comment above re grease hole drilling or otherwise??

Will I be needing to do anything to the parts that are in the engine casing or should I just replace the swing arm items.??

Anything else worth doing whilst I have the swing arm off?

Surely grease is grease ...or is there special stuff for swing arms - seen some comments re this somewhere.
