Just got all new front bearings from Georg.
Outer set is easy, but have questions about the inner wheel (inside the hub) bearings.
Are they press in, where I need to take to a machine shop? Or can I do it myself?
Can't really find a whole lot on this doing a mudsearch.

Trick to this Texican taught me.
Take outer bearing out and put nut back on.
Jerk whole knuckle off and it will pop back seal off. Bearing will fall out like front did.
Gotta clean all grease out of knuckle and beat races out. There are grooves you can see when clean to put punch in.
I use the old bearing to beat the race back in.
Fast reply...thanks!
Just to make sure I'm not gonna mess this up because I don't know what I'm doing, first below pic shows the 2 bearings I'm talking about. That's what you're referencing?
I'm asking because it looks like Georg also sent me the inner seals for the knuckles, and I wasn't planning on going that far in. Second pic shows what my fronts currently look like.

You need to take it all the way down to the ball on the axle. Upper and lower kingpin bearings....no.
That is the bearing I am talking about that you circled, yes/

Put the races in the freezer and they will slip right in. Trust me we have done enough of em'.
Don't be! You can do it!
Also, I would pass on those rims at $400. Seems high to me, and they look like the chrome has been painted. No bueno, in my opinion.
Thanks, we'll see...
I've asked for more detail on the wheels, and he's agreed to go scratch them up, make sure they are not painted chrome. If they aren't, probably going to do it. It's either these or the original ones with the hubcap clips, and I like these better. I'll get them sandblasted and powdercoated black anyway.

2 cents from probably the least experienced person here...
I think it will be self explanatory once you tear into it. It was for me on the 80, but then again there's a great how to for this in the 80 section.
I had hell replacing the wheel bearings and races in mine, but the trick Nolen mentioned seems pretty slick. When I read it, though, I assumed that in step two he was referring to jerking the hub/disc assembly rather than the entire knuckle itself. At this stage on the 80 that assembly will come right off the spindle leaving the axle in the state you have pictured. Which means you wouldn't have to tear back into it again. I figured the 40 was the same, but I really can't speak to that.
Either way, with the hub assembly off you can pull the rear seal with a seal puller, a big pipe wrench, or anything you can use to get leverage on it. Once it's out, the rear bearing will fall right out just like the front one will with the adjusting nuts and washers out. I used an old socket extension to beat the races out, put the new ones in the freezer like Jeff mentioned, and actually put them back in with a cheap bearing race driver set from Harbor Freight. I tried to put them in using a brass drift but didn't have much luck. I put the seals in the freezer too, and they went in pretty easy.
Again, this is just from my experience with the 80 knuckle rebuild, so take it for what it's worth...probably not much.
Good luck.

this hits conversion stuff but also covers rebuilding the fronts in general pretty well IMO

OK, got a question before I buy these.
These are stock wheels from an 81 FJ40. They measure 16", not 15", in diameter.
Question is will they fit on my truck without any spacers?

Wasn't aware they put 16" wheels on any 40's. you sure you are measuring right?
Never seen a factory fj40 16....there were factory 70 series 16s. Don't measure lip edge to lip edge. That will be 16 but I am willing to bet $20 those are 15s...
SOR sold some chrome 16's just like that a while back. May have been from outside the US?
