What does the white paint mark on the hub of the rear axle mean?

[Robert G.]

Does anyone know what the white paint mark on the center of the rear axle hub mean? How about the blue paint on the brake calipers, along with the white paint daubs on there too?

Bob -

Most likely in-process inspection marks from the component manufacturing plant.

Interesting that there are so many inspection marks on the car. I'd bet today there are none, but then the way they do things have probably changed.
In my line of business, the only inspection marks that manufacturing used were ink lines drawn across bolts showing that they had been torqued to spec.

Bob, take a few pic.s of the marks if they are original to your car. good documents to have for ref.

Paint daubs are still the industry standard where certifications are needed on components.

You wouldn't say that if you saw the build of the LS motors at Wixom Performance Build Center. They mark every bolt that is torqued with a daub of orange paint, even though the values are recorded and retained electronically.

Over on Corvette Forum some of the guys have posted the marks on the inside of those motors and it looks like Halloween. Oil drain bolts (there are two of them) get a pink paint swatch bridging the bolt and pan. I just today saw a green daub on the exhaust manifold of a 2008 LS7. Colored marks sill go on.

I had no idea they still did that. I wonder whether any foreign manufacturers use this method. It seems outdated when you see how high-tech the cars are these days. I have a Grand National that I bought new and haven't seen any inspection marks on it. When it was new I used to crawl under the car to wipe down all the surfaces to make sure they were clean and never noticed any.

Hondas made in the U.S., or Japan, or both?

Honda also has a plant in Alliston Ontario Canada that makes Acura's & Civics.
