Preventing Rusting Door Hinges

I just purchased my 1st Jeep (2010 Wrangler Unlimited Mountain) and every used JK I've seen, first point of rusting, is the door hinges. I have, and heard, several good explanations why, however I have yet to come up with, or hear a good idea how to prevent this seemingly inevitable issue. Any good ideas out there?

You could try drilling small holes in the bottom of your rear view mirrors. This allows the water to drain out of them and not trickle down your doors ( where the hinges are )

It seems the rusting is from water collecting in the hinge, since the 4 door jeep has it on all door hinges, not just the ones under the mirrors.

Just checked out their site, great tip. POR 15 might be a solid preventative solution too.

Thanks!

that stuff is great. Not cheap, but totally worth it. And a little goes a long way so if you do buy it, dont buy any more than a pint. You probably wont even use half that.

If you're going to TAKE the hinges off !!!

You better make sure the attachment position is ETCHED in ink, because it's near impossible to get them reinstalled in perfect pin/gap/airflow/gasket seal position

I had removed my front top hinges, to install my Rockhard roll cage and It took me hours of reattachment/adj to get them perfect, it's doable, but not easy

If you want to remove all eight hinges--GOOD LUCK !!

I was looking for the "easy way," hope somebody has one.. I didn't even know about the problem 'til I went in the garage and saw the streaks after washing (and drying it the night before) NO problem locating the problem, when you bought dark green...

I work for a Jeep Dealership Body Shop...We've done a couple repaints so far, mostly older JK's though (07-08). I just bought a 2010 beginning of June 2010. I am hoping I don't have to repaint hinges. One of my Painters has a 08 JK too. LOL

My wife's Jeep had the Tricare anti-rust module installed when we bought it, and it doesn't have any new rust on it since we bought it (it's an '06). My Blazer (without the rust module) rusted all over the driveway!
When I bought the Wrangler, I knew about some models that had hinges rusting (I saw one with bubbling at the dealership), so I immediately went with the module on this one too!

POR 15 is incredible, I used it on my trailer last year and it survived a salty winter and not a hint of the rust re-emerging. The MOST important thing is the metal prep; follow the instructions to the letter and make certain the surface is completely free of grease, goo and flaking rust. Poor prep = Waste of $$$$.

Is there no one that has a picture of the three hole idea??? Looks like a permanent solution (as long as you don't hit something with the drill bit) Also any suggestions as to bit size??? Thanks-

Hi,

I just brought my 2008 Wrangler unlimited to the dealer. I found rust bubbles on 3 out of the 4 front door hinges. So far no signs of corrosion on the two back doors. The bad news is that my dealer told me that both front doors show rust on the door body when they unscrewed the hinges. I'm afraid whatever they will offer as a solution it might come back as a problem in future. On rainy days and after washing my vehicle water poor down from the mirrors just on the front door hinges. The different materials of doors and hinges seem to work as a chemical element provoking the corrosion process. What about a plastic layer between the door and the hinges? Any help warmly welcome!!!

Greetings from France

My new to me 07 is immaculate, well-except for the hinges. PO touched them up. not really noticeable unless you look, but my jeep is black so.
You figure jeep would have this figured out. I never understood why they rust

Chemical reaction between dissimilar metals in door and door hinge causes a chemical reaction creating the corrosion.

All 8 of my hinges on the 4 door are all corroded and falling apart. It's driving me crazy!

Fluid-Film (Fluid Film® | Corrosion Preventative, Lubricant and Rust Inhibitor), every 6 months. $15 per aerosol can that will last 10 years if you use it only for the hinges. Also works great to prevent frame / undercarriage rust - just spray generous amount before each winter season. Two cans will suffice to get the whole car done. Repeat every year and you'll cut rusting by 90%.

Will have to look into one if these sprays. But man my hinges outside are a bullseye for rocks I spit out. 3 months old and each one has 3-4 chips on them.

Has anyone tried any of these?

The biggest issue is the door and body are steel and the hinge is aluminium. They primer it all and then attach the doors to the Jeep, the final process is paint. There's no paint separating the two metals, only a thin coat of primer. To properly fix this, you need to remove the hinge paint or seal the area between the hinge and body/door panel, and put it back together. I did this only by taking a razor blade and cutting through the paint edge around the hinge and bolts to minimize damage. I lucked out I guess, it looks ok and went right back into place.

Unless something changed since 2007, nope. When I removed the hinges from my 2007 there was bare steel and bare aluminum. No primer.

I'm doing my 2011 hinges this year as I've been seeing some white powder coming out from between the hinge plate and door skin. I'll know if there is any primer there soon.

For what it's worth, starting mid-year 2015 Chrysler has started putting a gasket between the hinge and the tub. No exact date known. Just passing along what I heard, for anyone who looks it up in the future.

I'd really like to know when this started. If love to know if I've got that sweet gasket without breaking down the hinge. I'd probably do more damage taking it off to check.

Good to know.. was sitting here wondering how I would address this but glad I won't have to.

For those with older version... I have an idea. I imagine even a simple layer of vinyl would solve the problem. Use painter's tape to mark the original hinge position. Remove hinges. Apply quality vinyl to the backside of the hinge and trim with a razor. That should create enough of a barrier and be fairly cheap.

I guess the folks in accounting must have finally come to the conclusion that the preventative measure is cheaper than fixing it after the fact. I would have figured that given the number of JKs sold, they would have crossed that threshold a long time ago.

That was my whole reason for making Chrysler fix mine under warranty. I wanted THEM on the hook for it, if removing the hinges the whole paint job.

Yes, when mine were fixed, there was some of the gasket material outside the hinges. It cleaned off, but it looked/felt almost like plastidip. Not as thick, maybe, and black.

Yeah, it HAS to have been ridiculous. I know one rental bill ALONE was $1700!!! I figured it was changed because I cost them SO much money in November/December that they finally cried 'Uncle'.
