- Repairing my 2012 WK2 Grand Cherokee Quadra-lift air suspension leak.
Found another youtubers ( Tim Adams ) video which prompted me to check for the same leak as his. Here is his video.

Where I ordered the part.

Just a quick update.. it's been about 1 year since the repair and still no leaks. System responds to height adjustment within 10 seconds of selection. I am still very happy with the repair.
Hey guys I know this is frustrating and hopefully I am not too late for some of you. It took me some atime but I think I got this. Follow this video but when you get into the WRITE THE SUSPENSION HEIGHT VALUES let the app read your truck sensors, then let your truck adjust its height and then STEP OUT FROM THE TRUCK AND MESAURE THE DISTANCE FROM THE MIDDLE OF THE WHEEL TO THE EDGE OF THE FENDER AND WRITE THIS VALUE FOR EACH SUSPENSION. After this your truck will adjust to its original height values, meaning this will adjust the normal, exit, off road 1 and off road 2 standard heights of your ECU System. Hope this works for you.

Hey, just commented in Tim’s post. So, just wanted to let you know incase you have a similar issue in the future, and anyone else reading this. I just fixed mine in about 10 minutes for about 10 cents. I own my own big rig, so always carry a selection set of O-rings, cause it stops me getting stranded for the sake of a 10 cent o ring. My set goes from 7/32”x1/16” up to 11/16”x1/8”. Inside the Jeep fitting where the supply pipe fits in, is a little double thickness o ring. So, using a small hook tip screw driver I removed it. Then, using a set of tweezers I replaced it with 2 o-rings of the same diameter from my kit and voila! It fixed the leak. It’s a little fiddly getting the new ones in, but doable at home. The whole o-Ring kit cost about 15 bucks, so at worst, the two o-rings were 10 cents, if that. Hope that maybe helps some folks. I know a replacement part is only Fourty bucks, but I’m all about keeping costs down and refurbing if I can 😊
That is an Awesome idea. I'll try that next time. Let me know how long its lasts.
Yea, I’m curious how long it will last too. From my trucking experience, I’ve never had an issue. When I’ve done replacements on the truck (three over the last 5 years) they’ve not failed again. Not sure if this being a nitrogen system will affect longevity of the new seals, but I guess time will tell.
@@NoClueH2 Hey, update on the leak post fix?
A year later and it’s still fine. Had to do the other side about a month ago. But, yea, so far, it’s all good.
@@NoClueH2 do you recall what size exactly you used?
I have had the same issue and when I shake that air line connector , I heard the hissing sound of air leaking . Thank you very much for posting this video.
Got the same problem with my 2015 Overland, dealer quoted me 200$ for parts and 300$ to change the whole line, i've ordered the connector for both sides and hopefully it works 🤞🏻
Same problem they told me 200 for the part and 600 to install . How did yours work out . I have 2016 overland
Did it work?
I have a 2015 Overland, same problem. I'll order the parts and try to upload a video.
beautiful truck. I love mine but it’s giving me the infamous problem
Thanks for posting this video. Dealer quoted me $1500 to address the same issue shown in this video.
Thanks brother, needed this!!
Use your link provided.
Sprayed windex on that plastic elbow and sure enough it was bubbling like crazy.
* for others...... You can electric tape/zip tie it in a specific orientation so it does not leak ,just to buy yourself time for the part to arrive so you dont empty out the system. I found slightly twisting the elbow and compressing the connection stopped the bubbling.
I love this air suspension but it makes you pretty vulnerable if.......when this stuff goes bad.
I think for all. That plan on keeping.A Jeep Grand Cherokee. Just put on standard struts on it. Otherwise,Just trade it in for something else. that does not have air suspension on it.
I had same issues but worse. My JGC 2012 they replaced both fronts ( extended warrenty) then it started again. Went to different dealership they did same thing one year later. 5 months later same issue. I change the top elbows myself from the reference youtube vid. But still same issue. 1st Dealorship changes right front for 3rd time! $2000. Not fixed.I fight and argue as I turn wrenches independently when needed. However the Jeep will burn the compressor up if use. I let it sit. They offer and do change valving block.No fix. I said , take the fricking time and locate the air leak in the line someplace. They dont.
Dealerships want to plug and play. Still leaking so now I am going to have to chase the damn leak myself. Hey Jeep reps.... screw your service and training ! That 2 stealorships I went to in different cities and both used the same ignorant protocol and could not facilitate the reasoning of continued leaks with all new suspension system ..TWICE.
I'm out thousands of dollars. I'll fix the leak I will post for others so they dont give Jeep more money.
No JEEP CARES is bull crap.Especially since its FIAT.
l8tapex hey man I fixed my air leak on my Jeep 2011 Jeep Grand Cherokee my hole air suspension broke but I fixed just the front for now for under 40$ and you fill it up manually like you do a tire and it holds and is so cheap
@@marcogutierrez180 well mine was back at shop.. so both top T's (connectors on shock top)have been replaced, The shocks were taken off the jeep and put in water / 55 gal drum under boost to see if the shocks have issues. They dont. We did the valve block change. Then my buddy re flashed the whole jeep and forced flash the level sensors. It only the front.Its seems to have made a difference but I do hear compressor run when I don't think it should. But it is not dropping when parked.
Did you get it fixed
@@marcogutierrez180 Hey Marco, how did you fill the air system? Where is the nozzel? How do you know how much to put in?
@@georgewilson1354 hey man so you actually have to replace the whole air system but I’ve found it was way to easy
Hey guys I know this is frustrating and hopefully I am not too late for some of you. It took me some atime but I think I got this. Follow this video but when you get into the WRITE THE SUSPENSION HEIGHT VALUES let the app read your truck sensors, then let your truck adjust its height and then STEP OUT FROM THE TRUCK AND MESAURE THE DISTANCE FROM THE MIDDLE OF THE WHEEL TO THE EDGE OF THE FENDER AND WRITE THIS VALUE FOR EACH SUSPENSION.

Mine won’t lift. The compressor just stays on so I just pulled the fuse to turn it off.
Do you have car running when testing for leak
sir where i can buy this parts cause mind too has a leaking anyone here can help me
were there any other symptoms beside the bumper sitting lower on the tire? noises or engine warnings/codes? was it low just on the drivers side or both?
how did the soap blow bubbles if the engine was not running, is it just from the air in the system leaking constantly?
from when you first noticed that the car sat lower on the left drive side tire, how long after did you repair the leak?
it's hard to tell if mine is leaking - have no error codes and seems to be level, but am worried after loud thumping and inability to raise up for several minutes last winter on a 9 degree day.
i also have a slight thumping that sounds like more right front passenger tire since it goes faster as i accelerate. also notice it turning right sometimes.
wondering whether we would need to recharge/fill nitrogen for the system or not if more of a severe leak.
When I purchased it... it already had the leak. Not sure how long it had been leaking) It always sat low in the front left when parked.. I noticed that the compressor ran a lot also( that was the main reason I decide to investigate what was wrong.)There were no codes. The lift system is a closed system, there is a nitrogen tank behind the back seat and the compressor pumps the nitrogen to and from the air shocks/bags.
Not sure about the thumping... could be so many things.. loose mounting bolts for the strut, worn wheel bearing, bad cv joint, tire out of balance, belt separation in the tire to name a few..
The crappy thing is that to diagnosis how much nitrogen is in the system, you have to take it to the dealer so they can running a program that calculates how much nitrogen is in the system.
Found your video while researching my problem. Rodent? Chewed through the hose that connects the part you changed. So if we repair that hose I don’t need to refill nitrogen??(2019 JGC)
@leeanpropes4197 only way to know for sure would be to take it to the dealer, thay can run a diagnostic program that calculates the volume of nitrogen.
However if after replacing that hose the jeep changes heights quickly you may be able to use it as is.
@@wildoutside9333 Thanks! Ordered the part for my husband to change out Sunday and will keep my appt at the dealer. Just hoping they will use my warranty if it’s over $100
I have noticed that the common denominator in almost all these videos seem to be the HEMI engine.......has there been a major report of the same problem with the PentaStar V6 engines and is there a certain time/mileage for this to happen?
Same problem with my 2014 Diesel
Can someone help me i got a 2011 grand cherokee overland with quadra lift air suspension, the problem is that the rear left side does not get over the first level as the other sides?
Did you need to get the nitrogen tank refilled after replacing that fitting?
I have not as of yet. The system responds very quickly now.
Since it's gotten cold it does like to adjust itself when I first Crank It Up so I'm going to assume that it had been leaking for a while before I had gotten the Jeep and that there is air in the system.
Thx for the cred. Good video! I assume it fixed it. Your engine bay is a lot cleaner than mine!
I’m trying to see if i have the same problem only thing is my whole car is not just the front
Nice video, subscriped.
Where did you order from
Rebuild master tech suspension products in Clear water Florida
I just did mine after doing them it’s not coming up like it should I tighten them way to much then after loosing them a little it started working but now when I ride it drops back down and my tires rub ? Any suggestions
Did you replace the connector or just tighten your existing one?
@@wildoutside9333 I replaced the elbow
It's possible the pump manifold is malfunctioning or the system is low on nitrogen. Unfortunately you either have to find someone that has the equipment to check the volume of the nitrogen in the system or have to take to a dealer. They can run a program to check the pump and the volume of the nitrogen. They supposedly check the volume of the nitrogen ,not the pressure. You can find the special connector for the reservoir tank online but you still have to find a way to measure the volume of the nitrogen.
My Jeep seems to be stuck on no 1 height setting .If I try to raise higher, just flashing
Hmm. It could be so many things.... height sensors at the wheels damaged or dislodged. Not enough volume of air in the storage tank. Compressor problems.. might be a good idea to have a dealer run a diagnostic on the system. At least find out if it's something you can fix yourself or have the dealer repair.
what did the dealer say? I have the same problem.
Me too. Third time this has happened. First dealer replaced the compressor $$$$, second the lines $$$ Third a fuse $ and here we are again. This time It's sunken on all for corners. Could not be more over it.
2 Questions, are those stock tire size and did this fix the leak?
Yes to both ..It did fix the leak, the tires are
Nitto A/T Terra Grappler G2 265/50 R 20..
mine is stuck on high and every time i have to let air out for it to come down? any ideas
What / where do u let air out of?
Kind of a similar issue. It goes up but then goes down, and the computer doesn't register it going down. It may be that the control module is acting up.... not sagging so don't think it's leaking but shows "Service Air Suspension Immediatley" on and off. Smh
Mine went to high and ran the compressor constant but only when it rained. Replaced the height sensors in the wheel wells and all good!
@@DRV-mt5dd so turned out to be the air valves that connected to the struts easy fix
@@jiovanysanchez6787 Glad to hear you got it fixed. Turns out the reason I am back on this thread is that I have a slow leak now, and just ordered new Voss/elbows like so many others have. Glad everyone helps each other avoid big bills from the dealerships!
HAHA just ordered mine yesterday. Passenger side is leaking, but im going to change both.
Hey man if the compressor does go out I have a cheap fix that I did on my air suspension
Here is the list of stuff you will need to replace the airlines your self
@@marcogutierrez180 nice, send me the fix
@@marcogutierrez180 what’s the list?
It’s not just the airline, elbow kits?
Did it work out ?
I guess it's been about a year-and-a-half and still no leaks. Actually created a update video I just haven't posted it yet.
