Rust on rear wheel hubs?

[slim_pickens]

I've got about 7k miles on my 2022 Wrangler Rubicon Xtreme Recon. Today I did a 5-tire rotation.

After pulling off each of my rear tires, I noticed that the wheel hub had a decent amount of surface rust. By contrast, the front hubs were fairly clean.

So two questions: Is this normal? And any advice on how best to clean these hubs and prevent future rust buildup?

My understanding is that taking a wire brush to these is OK but you should not lubricate these in any way because you want the wheel to remain tight against the hub. Still, I'm a little bummed these rear hubs look like they do after only 7k miles.

Thanks!

I brush them down and hit em with cold galvy paintas needed.

Normal. Front and rear hubs always get rusty. Paint them or spray with an anti-corrosion like WD-40 Specialist Long term-corrosion inhibiter.

I actually misspoke earlier. The rust I'm seeing on the rear is I think on the hat / cap of the rotor and not the wheel hub itself.

I know rotors get replaced eventually anyway, but would it still be worthwhile to brush these up and spray them with a corrosion inhibitor?

If you are in a wet climate or where they salt the roads, you need some protection on the hub flange and rotor, or they will rust solid and be a nuisance to remove when you need to do the rotors.
