One source of noise - rubber seals rubbing against hardtop - anyone else?

In all my attempts at quieting the cab of a noisy Jeep, I have been searching for this elusive squeak/creak that seems to be coming from where the driver's door meets the hardtop (freedom panel)...

Well, I finally found it. Where the door's rubber seal meets the hardtop is dry and clean, and when I hit bumps or uneven pavement, it causes a squeaking/creaking sound as the two surfaces rub together.

I put a tiny bit of oil on the seal to see if this was actually the case, and the oil silenced the noise instantly. Now I am looking for a rubber care product that would allow the seals to move against the hardtop without squeaking.

Which rubber conditioning product are you guys using and does it leave an oily film once it's applied???

Thanks for the input!

This is a source of noise on mine also. I pushed the door in from the outside of the vehicle and I could tell it was the rubber seal.
I figured there was no way of stopping it.

I figured it out by pulling on the freedom panel which reproduced the noise I was hearing while driving...
I am sure that treating the rubber seals with something slightly oily would solve this issue, by allowing them to move against the other surfaces without squeaking.

Now I just need to figure out what product will do that.

I saw two people mention that this product worked to silent squeaky seals: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
I ordered some.
If it doesn't work I'll try the 303 stuff below.
https://www.amazon.com/gp/product/B0...=ATVPDKIKX0DER

Otherwise, I am just going to find an oil or grease that works. Maybe something made for rubber bushings...

For any rubber squeaks and rattles we use a chemical called Krytox (I work at Porsche). Whether its door seals, top seals, etc, it works awesome and solves it on the first application. It's what Porsche has recommended.

Its called seal itch in the industry - we use armorall.

Your seals are coated with an anti-squeak / freeze release coating at the supplier - it wears off over time. Many times it gets applied a bit too thin to start with and can cause issues with itch/squeak from the start. Spec is usually around 50-100 microns I believe... but its spray applied so sometimes there are light areas. We just recommend you armorall them occasionally if there are squeaks...

I'm a seal design engineer... ironically - we were bidding on the new JK replacement business... not sure if we got it or not.

Yep Krytox works well also - we typically use that for glassruns..

You work in sealing also?

No, I work in service at a dealership. Lots of convertibles out there that develop some minor squeaks over time.

If you get the contract, I sure hope you take the job more seriously than the JK engineers. Far too many rain water leak issues from poor design.

I didn't think of Armorall... Great tip, thanks!

What do you think about trying Mother's Back-to-Black, too?

Not familiar with the product but a quick search for the ingredients shows that it uses morpholine as a wax like agent to give a gloss to fruits etc... so they probably use it to give a sheen back to trim pieces... it also contains butyl acetate as a solvent.

Armorall on the other hand uses water based silicone and no petroleum derivatives...

I don't see why either would harm your seals, although I think the Mothers would not be as slick and may actually case a "tick" as the waxy nature of the morpholine may cause the seals to stick to the door a bit. Once again - no idea based on experience, this is just a thought based on the ingredients.

Great answer, thanks... I'll try the rubbber protectant and armorall.

Armor all. Perfect. My 2010 just started creaking a bit, or maybe I just started noticing it since a friend of mine asked what was creaking. LOL. Gonna put some on the seals today.

Awesome timing.

Today, I took my freedom panels off and thoroughly cleaned all the seals and then applied the German Gummi Pflege conditioner...

I even applied some to the rubber bumpers on the hardtop that rest on the roll bar above the sound bar.

Honestly, I am little surprised at how faded and old looking some of the rubber was. Especially, considering I live in an extremely mild climate and garage the Jeep. Though I have been lucky to not have a single leak so far, so they must be doing their job!

I'll drive it a bit and report back about the difference in noise.

It is significantly quieter. It's amazing how much they were creaking and squeaking...
I had just got used to some of it and choked it up to the Wrangler's "character", but it's really quiet now.

This is the most useful thread ever!

I went and smothered Armor All over all rubber seals.

Finally found a use for that bottle of Armor All sitting in the garage

A high temp silicon grease would work just as good. There's one from Napa: 7651346 Sil-Glyde Silicone Lubricating Compound. I use it when I do brake jobs, on hoses, seals, etc.

I'm so glad I'm not the only one that creaks/squeaks bother. Its the best feeling in the world when you solve one or many. We both did similar things as far as quieting the inside of the Jeep. The more quiet the Jeep the louder the creaks are.

I agree. I enjoy chasing down some of the issues and fixing them...

I swear by Gummi Pfledge.

Three days after buying my Jeep, it rained and I had a small puddle on the passenger front floorboard.

I immediately ordered some Gummi Pfledge and applied it to all of the top and door seals. I havent had a leak since. Now, thats not to say maybe a top panel was over/under tightened. Or maybe my removing and reinstalling the top panels gave a better seal. Too many possibilities. But the germans swear by it for their rubber seal.

I dont know how often it should be reapplied, but I was thinking about doing it once a month. Heck, it only takes 5 minutes.
