Dkjeep's bearing arrived today. I chucked it in the lathe and measured the runout. It was a pretty close to 0.014". That's with the housing in the jaws, and turning only the flange.
After disassembly, I checked the runout between the spindle and the flange. It's all one piece. The runout was 0.0025"; significantly less than before disassembly. I chucked it several times in different positions to verify the measurement.
I haven't figured out why there is such a difference.
Other than the runout, I see no damage to the ball bearings and races.
The hub is identical to the OEM hubs made by ILJIN. The races are machined into the housing and onto the spindle, then locally hardened.
I could not find any evidence Dkjeep's assembly procedures outlined above had any direct relation to the hub's runout. It's more like the bearing was made that way, or suffered a blow from a pot hole or during wheeling.
The flange has a Timken part number, and TKR stamped into it. The TKR is a different font, and is deeper than the other stampings.
On the box, (this one and the one from a few years ago), there are the following statements:
"Distributed by The Timken Company.
Timken® Service Parts are carefully chosen from select manufacturers."
The box from a few years ago had "Made in the USA" on it. This new box does not.
The bearing from a few years ago had ILJIN stamped on it. This new one does not.
Based on the statements on the boxes, I believe Timken is still not making the JK unit bearings. The TKR is likely being stamped on the flange at the point of manufacture, possibly ILJIN, as in the recent past.
Once the disassembled hub is cleaned up, I'll take some pictures and add them to this thread: https://www.jkowners.com/forum/stock-...ing-study.html
