Suppliers include people "breaking for spares" on a regular basis, when purchasing spares members should ask a supplier what they contribute to the running of the forum particularly if contacted by a Private Message

I will have to agree with the alignment statement.
Yeah me too, a repeated failure like that would seem to point that way, in absence of technician negligence.
@me101, I don't have any advice, but here's an observation: a complete Gen3 rear axle can be sometimes had for quite reasonable money here on the forum. If the next bearing replacement is similarly short-lived as the last, maybe chucking in a used axle unit would help get you reliably back on the road.
@yakuza appears to take this approach; it always seems he is swapping out gearboxes just for fun.
Is it just the leaks? No noise or play in the bearing?
Then it sounds more like the breather.
Seen that a few times, just loosen the sticky top on the breather on the axle housing.
Koyo for wheels
Took a chance on timken for last kingpin change
They lasted a lot longer than I expected
Yep, KOYO I believe are OEM Supplier.
They are the only reputable manufacturer of these as far as I know - SKF, Timken, Nachi, NTN etc don't make them.
I would say they are a bearing originally made by KOYO for Suzuki specifically for this application - all parts suppliers I have come across only list Jimny's and samurai's as being compatible.
A 35 x 72 x 22 deep groove ball bearing does not exist even in standard form from SKF.
There are of course aftermarket manufacturers, the last cheap bearing I used was branded "Rhino", I'm sure you can get them made in China with whatever name tickles your fancy.
European manufacturers trying to save money from cheap bearings in China have lost millions.
Also pirate bearings marked SKF explorer are very good copies down to the box you get them in. Only minute differences can tell them apart with a trained eye like in the thickness of the cardboard box. I have seen them.
But of course the bearing life time is how you notice you have been fooled. Many shops have no idea and think they buy good stuff but they do not.
And of course not technical knowlegde people in the supply chain run by economist managers think they can save money but they get fooled.
And even if you buy parts from a reputable shop you can happen to get pirate parts or the former well known brand have since moved their production to a low cost or no cost place. And they do so without telling anyone in the supply chain because they now they would loose money if we knew.
I work in a company trying to make money from production in Norway. But with the prices we compete against it is a struggle.
But again with the economist managers we have no chance trying to explain the importance and cost of quality.
I have run SKF in the king pin bearings and they do fine but the standard 30302 J2 ones may or may not have the seal ring that the original ones have. The ones you get in here from Martin do have the proper seal, or had it the last time i bought them. That was a long time ago and they still work fine.
But back to problem at hand. Rear axle leaking oil.
A stuck valve in the breather, either filled up with mud and dirt, or rusted shut will force the axle to leak from heat expansion in the oil.
When the oil expands the seals will release the oil.
When the oil retracts its volume the seals will suck air.
The sucked in air will contribute to the leak volume the next time the axle gets warm.
It works like a pump.
just wiggle the breather cap with a pair of pliers so it gets free and can move. Or pry it off, clean it and grease it and put it back. You may want to bend the edges a bit to make it not come off by accident.
Or even better fit some sort of raised breather with a hose up high.
