Hey there, Carl. I just remembered you yesterday. I used to be your next door neighbor a few years ago. I just decided to see how you’re doing, and it looks like you’re doing well. have a good day.
As a yoke manufacturer, I have some questions and comments on your test. How did you ensure the splines on your shaft were concentric to the lathe chuck? If the pitch diameter of the splined shaft was not concentric, the runout may change depending on how the yoke is clocked. As far as I can tell, JantzEngineering has never purchased from us, so I have no dog in this fight. But thought it may improve the conversation to comment. I will also point out that how snug the yoke fits depends on the manufacturer. Dana, for example, uses a class 5 fit, which slips on by hand. On some of their medium and heavy axles they actually roll a slightly helical spline on the pinion to avoid play when tightened. Others use a more transitional fit that can require a press to remove. However, your main point is entirely valid. Seal manufacturers recommend a maximum amount of runout. That runout is actually a combination of the yoke and the pinion runout, since both combine to make the hub upon which the seal rides. As an Engineer myself, I pay close attention to runout, and strive to minimize it as much as possible.
Thank you very much for the comment. In the chuck is a front axle end, I chucked on the seal surface and dial indicated off the lathe center in the end of the axle. Tapping with a lead hammer till run out was under .001”. My chuck is in good shape, I have done similar set ups and checked the run out right at the chuck. It is usually under .002. I know a four jaw or turning between centers is more accurate, but this is plenty close for the job at hand
Wish you mentioned the company of the one in good shape.
Thanks for the warning,..😎✌

The parts industry is in a race to the bottom. Seems like I spend more time dealing with new junk parts, than getting anything fixed.
You may not want to mention the poorly made yoke but will you say the manufacturer of the yoke that got good reviews?

Man I’m glad I purchased parts from you sir!!
That’s it, time to manufacture some
J-Yokes
💪🏼
So mention the manufacturer that still takes pride in its parts
Would you be willing to do the Alaskan race again
Personally I blame squirrels
Rabbits. It's all rabbits.
Name and shame the shoddy companies or at least name the decent one.
