Exclamation Surface rust on 2014 JKU 60miles!?

Hey, so I picked up the jeep a few days ago and my buddy noticed rust forming on the control arm, and also where the shocks are mounted.
I know these parts rust easily, but this can't be normal for a Jeep with only 60miles on it!

I'll be calling the dealer tomorrow to ask about this, are they likely to fix this? Or what can I do to prevent it from spreading?
I've read about Eastwood Rust Encapsulator, has anyone used this product or similar? Has it worked for you?

Also, I will be having a full Krown undercoating done this week, I just don't want to have them coat something that is rusting already.

Thanks guys!

This is normal, and actually beneficial in that it apparently hardens into a protective barrier that prevents heavy rust formation. There is a good explanation posted somewhere if you Google it. That's what I did when I wondered the same thing. Look at the drive shaft. It will likely look pretty rusty too.

I picked my new Sahara Unlimited up a week ago today and crawled under it for the first time today. I'm seeing the same rust on a lot of different components. This may be normal, but I don't like it! My last dozen vehicles have been Lexus sedans and SUV's. Rust on a Lexus undercarriage isn't the norm. I bought the Jeep for use on the beach in summer and for commuting on snowy days in the winter. A Jeep is a Jeep I guess. Plan on having some fun with it, but it's a secondary vehicle for me.

The factory isn't that good when they finish the frame and suspension for some JK's. The dealer will rattle can it if you complain. The drive shaft isn't finished (painted) and it shouldn't be.

This happens while your wrangler is in transit. Usually if it is on the lower transporter level, and gets the salt from the roads splashed up onto the undercarriage. And yes, the factory doesn't do a very good job of painting the undercarriage!.

Should it be there on a new vehicle, no, but it's not going to hurt a thing!!!!!

My plan was to Fluid Film the undercarriage on a yearly basis. I like to take care of the vehicles I own. I'll have to get rid of the surface rust on my week old Jeep first before I Fluid Film it!

Here's what I was talking about above. Rust on brand new jeep - JeepForum.com Apparently it's a process called passivation as explained here http://en.wikipedia.org/wiki/Passivation_(chemistry)

I have found the best treatment is to find a big mud hole and drive through it, thoroughly coating everything under your Jeep. Voila! No more visible rust!

To be honest they don't do too good a job of painting the top side either, but that's another story!!

Alright so sounds like it's nothing to worry too much about. I guess I can still ask the dealer what they can do about it.
I'll post some pics up soon

You'd be better off with a rattle can of rustoleum than you would by expecting the dealership to do anything more than say it's normal.

While that is true of Aluminum and Copper, I don't think it's true with Steel and Iron.

This has been argued on the Jeep forums for quite a while. It is also on the forums of many other manufacturers not just Jeep. Not every vehicle will have the rust but many do. If it was detrimental to the vehicles something would be done.

Here's whats happening. At least the dealer should wire brush it off and put some temporary rust spray until I get it Krowned this week.

Not sure how that's any different than seeing a drive shaft that has one side covered in surface rust, or heck, a drive shaft with surface rust period. It's not like the surface rust will settle or form in a perfectly even layer. How would a very thin coat of rustoleum be any worse?

Agreed. I've had plenty of vehicles with painted drive shafts from the factory. Jeep just doesn't believe in putting out an overall quality product from what I've seen. They have a captive audience with Wrangler owners. There's nothing else on the market that competes with it, so they cut corners and get away with it.

Don't blame Jeep. Like I said previously, you can look on F-150, Mustang, Toyota and other user forums and see them complain about rust on underbody parts.

Or their supply chain is bad. One or the other. For a vehicle like the wrangler, the price is a bit high, objectively speaking. But, people pay for it and that sets the demand.

It's just surface rust. I sprayed an aerosol can of Permatex Rust Treatment (you can get it at Autozone and O'Reilly's) on it and have moved on.

The Permatex Rust Treatment is thin, not a paint, so it won't affect driveshaft balance. Rather, it converts the rust to a translucent black finish. Google says it's an phosphoric acid that turns the rust to iron phosphate. I've used it a few times before and it's held up well. Most importantly, it doesn't require any surface prep - just knock any big rusty bits off and spray it on. Therefore, you can easily spray it on painted parts where the paint's chipped off. Also, if it does start to surface rust again, reapplying is super easy.

I used a high end rust remover and repainted my driveshaft & axle. Used rustoleum (sp?) flat black & it came out great! Still looks great & no signs of rust after a year.

Dunno, but likely. I think most rust "reformers" operate similarly.
