wheel locked up

The day before this happened I went wheeling and drove her home. She drive fine the three miles home. The next day I was about five miles out and the right front wheel started grinding, then locked up, gave a loud pop, freed back up but continued grinding.
Got her home, tore it down to the spindle, nothing. Put it back together and she drives fine.
I don't want this happening in the highway....should I replace the bearings or hub anyways? They are near new....
Thanks....

That almost sounds like a brake sticking. How bad was the grinding?

You should fill out your profile so we know what you're dealing with but I agree that sounds like a sticking brake caliper.

I've never had a bearing go from bad to good, but I have had stuck brakes loosen up spontaneously. The u-joints are OK? They can make all kinds of grinding and popping noises.

You really should fill out your profile if you want the best advice....

So the 'wheel' bearings are ok. That leaves the spindle bearings in the core of the spindle that the axle spins on 'If you still have the hubs locked' or a bad U-joint, again if the hubs are locked.

Sorry about the profile. Between my naps and the honeydo list I usually just wear out the search button when I have a question.
Thanks for trying to help me regardless.
As soon as I finish this post I will get right on it.
It's a 78 CJ5 Renegade, all stock suspension but for some shackles that I replaced and the usual wearable items.

I know it wasn't the spindle bearings and u-joints because I was riding down the road in 2wd, with unlocked hubs...sorry shoulda made that clear.

When I took the wheel off and turned the hub, I could hear and feel the grind - once per revolution, not a constant grind. Dismounted the calipers, same thing.

When I took it down to the spidle, the spindle turned fine, looked good, turned good. All the bearings looked clean and when mounted spun fine. I couldn't even find any major scuffing...and by that I mean something I could feel...not the slightest roughness on the spindle.

I even cleaned out as much of the grease as I could and looked where the bearings mounted - didn't see anything.

The only thing I found down there was that the seal was bad.

Off to update the profile.

Once again, sorry about the profile not being filled out and not mentioned the 2WD/unlocked hub status.

I would guess that maybe you picked up a rock through that bad seal or even had one caught in that rotor splash guard thing. I have done this from wheeling and rocks make bad grinds until they crumble.

So no worries then?

Thanks for all the help guys. I know I don't post much, but I have taken all of my advice/plans from answers/searches here, and have always been happy with the results.

Most of the time, I find that anything I could ask has already been asked a few hundred times over.
