Hi guys,
so i bought this hj61 about a month ago, still doing some stuff to get it registered here in Germany.
I went by the garage today to do some work on the front lights and i noticed this oil leak on the front left hub.
I'm a newbie, but this is pretty clear. I've only done around 600km since i bought the truck. The truck is been sitting there for about a week and there were only a few drops on the floor.
This means complete service of the hub, right? (both so to keep it even) Never done this before though, but I'm positive about it.
Any advice is welcome!
Thanks👋

That's "normal" "rust control" for 30+ year old hubs. Just make sure the knuckle cavity is filled with grease and drain & replace the front differential oil every year (if it's getting mucked up with grease) and you're fine. Otherwise, disassemble the whole works and replace the seals (and trunnion bearings while you're at it)

I knew I'd stumble upon this out of my comfort zone fixes. That's the price for riding such a cool rig!
 
follow the FSM directions and torque specs. Don't get your shims mixed up. Tear all the way down to the inner axle seal and pull and replace it.
You'll need a knuckle rebuild kit with or without wheel bearings. But do make sure they have the trunnion bearings.

And get this stuff:

At least 4 rolls of paper towels, 2 lbs of moly grease for the knuckles, 1 lb of wheel bearing grease for the wheel bearings and wheel hub, a box of latex or nitrile gloves, 2 cans of brake cleaner, a brass drift, a snap ring tool, a tie rod pickle fork or separation tool (or a big hammer), a seal removal tool or medium pry bar to pull the axle seal, and a spring scale to measure pre-load on the wheel hub and the knuckle.

Optionally you can rent or get a loaner knuckle centering tool if you have reason to think its not centered. If you go that route you'll need a caliper tool to take measurements.

You'll also need 54,24,19,17,14,12, 10mm sockets. and a torque wrench that can measure 20 to 90 ft lbs.

I priced someone here local doing it for me. No idea what sort of money it would take where you are, but here in the states, the quote I got was enough to force me to get real comfortable with this fix. $400USD in parts depending how far you go with it, a little time, and you should be set. I don't think its really all that difficult, just messy and time consuming. But definitely study the FSM on it. I also like the OTRAMM knuckle rebuild videos to get a basic idea of what needs to be done.

Doing as @OSS suggests is always an option. Yours does not look nearly as bad as mine. GL. HTH.

This is great info. Thanks a lot!
I went today to check if the puddle got bigger, but no. So it's not as bad as I thought. Anyways I'll make sure I get everything before I go down this path, as I need to rent a workshop place in order to do it properly.
Thanks again!
 
Just a simple reminder that I didn't do after my axle job. Check your front axle breather. I did mine and 2 weeks later pissing oil out of seals again. I reopened both sides trying to figure this out. Blew into the hose with breather completely blocked/rust frozen. Just love that New England patina lol. Good luck
