This video will show you a quick step by step way to repair a leaking quadralift suspension or air suspension on a wk2 Jeep grand cherokee. parts needed can be purchased here: www.amazon.com.au/RMT-JWK2-A2...
I woundn't suggest you let the suspension "compensate with regular air" @5:39 Get the nitrogen refilled. Because regular air contains moisture, and in very cold weather moisture can cause freezing, and freezing in the air suspension system will set off the "Service Air Suspension Immediately" alert and that causes havoc on the air suspension. It wont go up and down until the weather warms up again. Take it from me I had a headache with this air suspension until i learned exactly how it works .
My man! Had the same issue for weeks and got progressively worse. Searched a solution and found your video. Bought the parts on eBay (I work in the Middle East so it took a little longer) and then I followed your instructions: a five minutes job and the problem was solved! Forever grateful!
OH btw, to whoever read this, both sides are connected on same circuit, if one side of your front suspension leaks, both wheels are going down. Same on the back. They are just 2 circuits. From the compresor goes back to the tank then from the tanks coms back to the compresor (where the system that sends the air to the air springs is) and then 2 hoses comes out from it, one for the front and one from the back, They are connected in parallels.
GREAT! I hit the fitting when I replaced the motor mounts last night on my 2013 5.7L. Going to get the fittings, but I also found both of my upper A arms have bushing play, and my compressor seems to be getting louder. LOVE this jeep though, so I decided to get the 2.5" retrofit kit and ditch the air suspension. Probably in the spring. I enjoyed it for 7 years, but would like to run 33" tires all the time.
I just started having this issue on the front on my 2014 ram 1500. After seeing this video, I jacked up the front end wiggled the air connections back and forth several times. After driving it around a while, it fixed the problem after being broken for a week. I'm sure the nitrogen has already leaked out of the system, but it seems to be functioning again. The system kept flashing a message that the motor was overheating and it needed to cool down. So hopefully the motor didn't suffer long-term damage.
Good fix for leaking connections. I should add that in fact it is a closed system with nitrogen reservoir under back seat. It can exhaust pressure to atmosphere but does not use outside air to add pressure, but nitrogen from tank. If the reservoir is low on pressure the system will shut down. The fill procedure requires a scan tool (I have WiTECH) to actuate the air valves along with watching the pressures while filling the tank to 175 psi. Then follow with "air mass" tests and ride height calibration. I learned all this on a 2011 that was totally depleted. It was very stubborn performing the reset tests, now I know that the compressor is weak. I believe that the system can compensate for leaks but need a strong compressor to otherwise work properly. In my case there were several fault codes in "ASCM", (C2212,C15A1,C1562) I think this case is much worse than yours with leaks.
I've a got a 2011 Overland. The previous owner had the dealer replace the compressor and fittings on the air shocks at 105k. Only reason I know this is due to the previous owner keeping all service records with it. I bought the jeep at 125k and it seems to be doing the same thing.
Thank you SO much for this video. My GC was leaking for long time, and then I saw the official video to "refill the nitrogen" and I thought that I was screwed, that I need to refill the system somewhere. Thanks for letting me know that the system will refill itself. I have the link on the exact same place
@@nh9127 Yeah with official I meant a certified mechanic mad ea video on replacing the compressor and the procedure of refill nitrogen. Here is that link ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-r_UtE9o6gPA.html
Thank you for this video, since you change this part is there any issue with it after that time? I have the same problem and I worry about the quality of that item
Thanks for the vid. Cpl things mate Plumbers tape on the threads and soap and water for the leak check. Thanks again!! I just started getting chime..... service air system immediately..... First thing I am doing is taking your advice.
Funny I just bought a 2013 GC with Quadralift, Hemi, QD2, anyways I thought I better buy a few of these and sure enough the driver's side is leaking, just changed it. It was from the air line getting stressed by whoever last changed the air filter, pressing down on the line.
Great video. Unfortunately it didn't solve my problem. With my car, there is no air leakage. There is no air period! I'll keep troubleshooting, but thanks again for your detailed video.
You SHOULD worry about air being in they system. Nitrogen doesn't allow water to enter the closed system. Moisture is the cause of failure for many air suspensions. Also, nitrogen molecules are larger than air molecules making it harder for them to leak out. Finally, nitrogen is not affected by temperature changes. When air gets cold the pressure decreases so your suspension filled with air will sag in cold temperatures. This is why Jeep designed and filled the quadra-lift system with nitrogen in the first place; for better, longer lasting performance at a wider range of temperatures. When you fix your leak have the system topped up with nitrogen. Low levels of nitrogen will lead to your system not being able achieve the highest ground clearance.
Hi! How do you refill the air bag once you have replaced? Can you do a video on that please? Where do I put the air into? I cannot find anywhere that will do nitrogen I'm on the Gold Coast
I'm having this issue for weeks now on my 2012 JGC Overland Summit. The rear suspension goes all the way lower than the front suspension. Sometimes it takes time to level up. My question is "do these two parts work for both front and rear suspensions or only work for the front suspension? Your quick response will be appreciated.
My jeep overland was sitting on all four wheels replaced the valves on front struts reset system and now after about 3 hours rear now sitting on tires and front stays up
I'm thinking of replacing my solid and dependable Cayenne S to get another Grand Cherokee, the air lift of the Porsche has been rock solid and she is now 17 years old. One height sensor after kerbing a wheel is all its ever needed. On the whole how reliable has this been as a Jeep and how many issues have you had with your Quadralift? (Years ago my WH/WK CRD was good but not perfect) Is your the Diesel of Petrol unit? (realised I was early to ask - you're has the HEMI) - note you're sounds like a CRD at @ - i'm confused Best wishes from the UK and thanks for a great video.
@@ulrek54321 I still have the 2004/5 Cayenne S, it has the V8 and air suspension and still extremely reliable and capable on dirt roads. It’s capability was like my WK with Quadradrive and Mercedes CRD diesel. The differentials are 4:10 like the Rubicon and the transfer case is 270:1 as opposed to my my WK which was 272:1 Thanks for the info, I really appreciate the thoughts!
hi thanks we hold GC 2013 overland I am trying to locate the catalog number of the item and its exact name in order to purchase and I would be happy for help on the matter
You could replace the pump assembly for ~1k which makes doing this cheaper than one single visit to the dealership for quadra lift. Even if it means you need to buy a new pump down the road. They don't want your business just based on the massive markup involved in their service prices.
Hi. I have been facing this issue for months now on my 2014 GC Summit. The front right side goes all the way lower more on to right than left. Have tried to replace the suspension itself at a big cost but no use. While driving it comes to normal height.
@@luisgarage8773 yeah the lines are leaking and I get the hissing sound while moving the part. What's the part number and from where can I buy this. I live in the middle East. GC 2014 summit. Please let me know the part number.
Check to see if your compressor is working, you should be able to hear it come on and off. If it runs constantly or very often then you might have a big leak. Try spraying all the lines with soapy water
Hi, I drive the 2013 jeep grand cherokee 5.7 hemi and the air suspension is not working, the back wheels aer up and front down, i cannot really drive the car and there seems to be no air at all. What could be wrong and how do i go about fixing it myself?
Hi, I have a 2011 GC Overland and the rear is up and the front dropped on park. It used to rise to normal height in starting but doesn't anymore. The pump still works but I feel I may be out of oxygen
about to buy mine on amazon quicker deliver take note ebay sells one that has white tips do your research i think that is a different. local dealer quoted 4k to 20k to repair no joke lol
It's sad that the dealership would charge you thousands for ten minutes of work with parts that cost 60 bucks. Also keep your vehicle overnight so it doesn't seem like they robbed you
I’m about to get this but I was thinking, could I just take mine out and put some RTV silicone on my line? I feel like that would stop the leak just as well but I kind of wanted a second opinion on that 🍻
The dealer does not sell the part, you have to get it from here rebuildmastertech.com/jeep-grand-cherokee-2011-2020-quadra-lift-suspension-front-rear-air-strut-spring-bag-repair-kit/
