Only way to approach it is to get all the parts for a full hub rebuild or strip, inspect and get required parts.

Depends on time and money constraints but I would go for all bearings and seals in the hub.

Same as Sniper says - couple of good vids on YouTube - one by our own Martin Lines HERE

...and a more detailed one that shows potential problems that can be encountered and how to overcome them found HERE

You should be able to do this yourself if you're mechanically minded and assuming you have a good set of tools, a suitable jack, and some axle stands for safety ;)

Yes it's common and is made worse (just my opinion) by rust on the swivel surface killing the seal. Once the seal fails water makes it way to the lower kingpin bearing which rusts, then fails. This causes movement in the hub assembly, which can result in steering wobble, but eventually the inner half shaft oil seal fails and oil from the differential makes it way out. That's the oil you can see on the tyre.
They don't last for ever, but rusty water just accelerates the problem, hence why waterproof grease is recommended.
It's an easy fix, £25 ish for just the bearings and shaft seal, £48 ish for every part including the swivel seal. Can't myself see any point in changing the swivel seal unless you remove the rust and refinish the swivel surface, rust is just going to grind the new seal away rendering it useless for anything smaller than dust.
As said above have a look at the video's (they are very good) and get the bits from Big Jimny Store, they are top quality.
It's quite a satisfying job to do and not difficult, it's a Jimny ownership rite of passage. Have fun.

Yes it does appear to be all you need.
But
Chinese bearings are at best rubbish and OEM parts are designed to last the warranty of the vehicle, not 12 months.
You are only saving £25 over known good parts (OEM Koyo bearings, Suzuki seals) and it's 3 to 5 hours to change both sides.
I appreciate not everyone has the extra £25, but if you do think hard.
That said they could be great.

Think you will need some decent greese too, hopefully someone will confirm this as I have the mechanical knowledge of a wooden spoon.

Your knowledge is impeccable.
Yes some good waterproof grease, also sold in Big Jimny.
Not connected to the store in any way.

The above is all true but I would suggest that a pair of kingpin bearings and inner axle oil seal are all you are likely to need along with some decent waterproof grease. All available for less than 35 quid from the bigjimny store. In order for the swivel to leak like that what has to happen is the drive shaft has to be applying uneven pressure to the inner oil seal allowing axle oil into the cv chamber making a runny mess, this only happens when the kingpin bearings have failed making the whole swivel assembly move outside tolerance. A messy but relatively simple fix.

...Unless like me - I couldnt get the left assembly back on as the bottom bearing kept dropping out! Could be easier with someone helping you do the job.

Looked like mine did, but yours looks more oil like, I think mine had an unhealthy amount of harbour hill pond water mixed into the diff too.

I spoke to Martin and bought the bearings, seal and grease. Changed today, it took me longer than 5 hours but some of that was getting a socket the right size to push the old bearing out.

I've never even done brake pads before but following martins video and one by 'mech it better' I actually quite enjoyed it. If I can do it anyone can, although I won't know if I did it right until I can get new tyres and mot though.

Good luck

Excellent !

I'm sure you did a first class job.
If its something you've never done before, just think it through and do the job slowly, checking and re-checking your own work as you go.
Et voila!
