Looks like a great outcome in light of the cost verses the cost of a 5 gallon pail of Evap o rust.

FYI Rust 911 concentrate is only about 4.00 a gallon when you buy the gallon bottle which is enough for 16 gallons.I use it because it is comparable in results yet is much less then evaporust . https://www.rust911.com/rust911-ultra-concentrate-rust-remover-dissolver-treatment-free-shipping/

I should have pointed out that my advice to use WD-40 was for parts that were to remain natural and need to be protected from rust.
Obviously a person doesn't want to oil down anything that's to be painted.
I think you have over-thought your predicament. Just re-dip your axle housing in the citric acid treatment. It's a great cleaner as well as rust remover. It'll take off the WD-40. But rinse with hot water this time and skip the wd40! Dry thoroughly and apply primer and paint.
Merry Christmas and Happy New Year!
