2006 Ford Expedition air shock creaking Sign In

After driving for about a half hour the right rear air shock starts creaking. Sometimes it doesn't but most of the time it does. Here's a pic of what is making the noise. It's got 160K mi, should I just let it go or take it in? Any recommended fixes?http://autoforums.carjunky.com/photos/pic/557KznWl/1681.jpg

Why are you so sure the noise is originating from there? I have never heard one of those air suspension bags make a noise.

Neither have I. OP, is there a condition that makes it worse or NEVER happen like in rain or even just wet? There's a lot of rubber bushings for suspension parts even if the pic that shine up rubber to metal just "so" sing away then don't.


If you really could nail it to one (area?) try harmless things if you wish like most furniture polish (There are several on my list to isolate "creaks of the sort" that should be harmless but make it quit longer than any normal return of noise. If so say so can suggest stuff that has worked for me was what I mentioned and takes a few applications to buy years of quiet. Again, it was never those air bags rather the bushings A-arms, lower strut shown body to frame donuts etc the culprits,

I got under the vehicle and pulled on it to get it rocking and it was clearly coming from this spot. I have a good video but not sure how to upload videos here.

If it's truly coming from that air strut, then it needs to be replaced but I still think you are wrong about the source of the noise.

I'd be more inclined to blame dry ball joint than the strut. You should be able to touch the spot and feel the vibration when the noise occurs.

Re: 2006 Ford Expedition air shock creaking Sign In

Hammer Time - I guess you are probably right because that material isn't conducive to creaking sound. I can't replicate it now so I guess I'll go for a spin and see if it will act up. Thanks!

Real grease - no! Why - you may not be sure item's rubber is real grease, oil friendly and cause a problem. If anything find it using harmless oil tells you it's bad there if a joint OMG it's go to go.


If just squeaking rubber like finger on glass when it's clean with just water/finger probably not worn out just too shiny for each item at the time. Those if little to no consequence I do lube start with WD-40 shut them up but is water soluble so follow up with rubber friends water resistant spray lubes have had luck.
AYOR if rubber goes all FUBAR on you, you chose wrong so read products, water tolerance - all that. Not yet but waiting for more physical pure Silicone spray grease that firms up to grease yet flows like a liquid to get at stuff. Close if white lithium in spray so far OK on bushing rubber on stuff ages old now of my own others long since wore out their vehicles plain used a lot - mine are not,

What Tom is saying real important.

Never use petroleum based products on rubber. Silicone based lubes are best.

Re: 2006 Ford Expedition air shock creaking Sign In

Posts out of order lsorry, web slow where I am! Right - Silicone for rubber or what looks like rubber if unknown. Petro products will dissolve rubber and ruin good stuff.


That shiny area if you took or have take all the tons of pivoting OR cushioning "I call donuts" where body rides on frame metal shine up unseen and squeak too as frames twist a bit.


The noise IMO if that is mostly harmless just so OBNOXIOS sounds like a real problem and repeat IF THAT is not serious to safety.


THE downside is real silicone is al HELL to paint over if that's some coming event repels almost everything. You should also not want a lube to collect road dust and dirt could fall off and harm friction parts (brakes) so ones that are targeted just where you want mean spray nozzle stuff that applies thin and firms up is best - I do whole vehicles of my own so silent with body ride or just torque of road surfaces.


Brand name now for assorted not just the FISH oil of WD-40 got into this assortment AYOR is costly I haven't tested them all so from me can't say all are known harmless or work yet.


Odd and personal to me noises that are harmless (must know that) make a vehicle (any brand/type) sound like crap, old and or worn out just a pet peave with me about 100% solved but takes time like most good efforts taking care of things.


A side benefit is same on items that may corrode (your's for 2006 +/-) looked good in general you already beat average life by time of a motor vehicle - really - check?
