The Unofficial "Ask a Stupid Question" Thread

Not sure, but back in the day on TSTSNBN the theory was to line the wheel lug hole closest to the valve stem with the yellow stud to avoid vibration.

I always thought it was where the locking lug nut was mounted. But Rodeo's thought makes sense too.

Who knows...

Yeah the theory was that the yellow was where there was the most runout on the hub.

Personally I think the paint is simply an inspection mark… “ yep there’s 5 lugs, send it down the line”

Don't we know anyone at Ford who actually knows?

Inspection mark sounds logical. There's nothing in the Ford workshop manual saying anything about aligning the valve with anything.

A guy I used to work with was a line worker. If I run into him I'll try to remember to ask.

The huge thing that gets me with that theory is I’ve bought brand new Cobra hubs from Ford when they were available, there’s no markings on them whatsoever. If there was a point of excessive runout wouldn’t that be most likely done by the supplier of the hubs? Who was putting the marks on them? The end assembling them into the spindles? The end installing them into the suspension? The end installing the suspension into the chassis?

That plus they’re so unsubstantial if it’s runout, the direction of the wing indents in the Tbird centercaps would have as much effect

I have also replaced them, and there's no mark.
I remember being told the same thing tho.
