mine did that but just last month Illinois. dealer said block. changed it charged it no codes wont work?

Thanks for the info . I want to do this as well . How did you vacuum the system ? I am guessing there are KZfaq videos demonstrating how- but I am having hard time finding them . Thanks

kzfaq.info/get/bejne/e76ppcyZ17-bias.htmlsi=CWrcmfnyZFmrKL7t This guy give a good example on how to vacuum the system, helped me alot

No problem

They want to charge me an extra 2k to follow through with the valve block replacement. Anyhow, I’m going to do it myself. Do you know of any write up’s or videos of the valve block assembly replacement?

Attack life standing up. You'll be fine.

Based on experience playing with these, the system self regulates. It will release tank pressure until it sits between the pressure in the front shocks and the back shocks. It does this once, and then it's happy. I assume its trying to minimize the pressure differential so the compressor has to work as little as possible when moving nitrogen in and out of the shocks.

I'll be honest, I'm not 100% sure how it works, but I'm fairly sure that even in the event of a leak, it will naturally aspirate to and from atmosphere. If you want to be sure your clear of leaks, inflate the bags to full height, remove the air ride fuse and monitor the height over a few days. You'll soon notice if one or more corners start to deflate. Outside of that, be lucky. Worse case, you'll be riding on your bump stops which isn't too bad for short journeys. Just to put your mind at rest, these systems are pretty good and reliable compared to many other manufacturers, so have confidence on your trip. Your truck will know if your doubting it's ability 😉

@@grizzlyfn393 We completed our trip and lowered the JEEP to Park Height on every stop. All worked good. Really enjoy the feel of air springs. I bought the adapters to connect to the Nitrogen tank under the back seat. Might check it out sometime.

If you watch the video, it clearly explains the reason for the pressure loss. These systems do not take air from the atmosphere, they are completely hermetic. The whole point of the hermetic system is to avoid moisture from entering the system.

@@grizzlyfn393 sorry but that is not a correct statement. there is a line that runs up behind the right rear tail lamp that has a filter on it where the air can be brought into the system if required. I had a leak in my ram and the system continued to function by pulling in outside air.

@@jbjohn21 👍

I was also lead to believe that it was a closed system by the stealership, but yeah it's an open system. I had the stealership completely swap out my system because they said it was all buggered. Many thousands of dollars later, I now have all 4 airbags and the compressor/relay valve assembly.

This system has 2 sides. One closed Nytrogen side and a side with outside air. The system regulates the height with the outside air, but in the suspension itself it's only nytrogen. That's what makes it a little complex looking at the space they had to place all that stuff.

The fault was air suspension immediate service I think. Once I deleted the fault, it didn't return. 🤞

Park it on a level surface and raise the truck to full height. Measure the distance between the floor and the top of the wheel arch on all four wheels. Pull the fuse from the air suspension and leave it for 24hrs. After 24hrs, re-measure the distance between the floor and the wheel arch. If the truck is lower on any corner, then you have a leak.

It now works fine. Please bare in mind that there wasn't anything wrong with it until I removed the rear axle and let out some nitrogen.

i agree 100 % had 2 so not anymore will i have an air ride system dodge ram

I'd much rather have the air suspension Ram. It has a much better ride quality, it also self levels the rear end when towing or hauling a heavy load. It has the ability to increase ground clearance for offroad or snow. It also helps increase fuel economy on the highway by going into aero mode. Too many benefits over the regular coil spring suspension.

Why not.

I only asked because you only have them on the front I thought after you installed the fronts you had buyers remorse

Do you know if that is 175 in both tanks or just the front one like this guy fills.

I think so

Is there power going to the compressor when you ask for it? Could be a relay.

No, when I push the raise button nothing happens. If I could find the relay I’d test it. Where is it typically located?

@@kimberlyjohnson3375 it'll be in the fuse box. Check the cover of the fuse box for the location or check your owners manual for a diagram. Some relays will the same so you can swap them around to see if it's faulty.

what was it ? did top button light up at all? tia @@kimberlyjohnson3375

Thanks for your comments, thanks for watching my video and thanks for the thumbs up and thanks for appreciating the free time and effort spent on doing this. Knob.

@@grizzlyfn393 Grizzly, thanks, the video was very useful. You can pick up regulator and air connections for about $65. About $110 for a small tank if nitrogen. I also bought a vacuum pump to help get the moisture out. If you want, you can reach up to access the ports from the underside of the truck, without tearing off the fender well. Mine originally had issues with the cold but was good after I warmed it back up. Now I'm having issues all the time. This time I warmed it up, refilled, raised the suspension, refilled again (per the manual) and then pulled the three fuses and the relay. Hopefully if the valves aren't opening any and it will hold the suspension for a while. Frustrating as hell. I'm waiting on a valve body, but there are no pumps available anywhere!

@@michaelosvatic7506 what was your outcome after doing this? Did it hold?

@@johndespenas1539 No it didn't hold, but I've learned a lot since I posted here. If you are having compressor issues, there is a good chance you have a bad air shock. The compressor really does not run much when the system is sealed and working properly. These are slow leaks and are not easily detectable. Last year my rear shocks leaked, but only while I was driving. The compressor normally refills, so you don't know its happening. To determine which shock is shot, get the truck up to ride height and the pull the three fuses and the relay for the air ride system. Measure the fender height on all four tires, then drive it or let is sit for a few days. Remeasure. If any of them change by more than, say 1/2 inch. It's probably bad. You can let it go longer to know for sure. After the shocks are fixed, then tackle the compressor/nitrogen. I replaced my compressor twice (first with aftermarket, then with factory) before finding the bad shocks. I'm guessing leaks go unnoticed for a long time as the compressor keeps refilling them. It's not until the compressor either gets tired or freezes up that anyone realizes it. I replaced rear shocks and compressor/valve assembly last year on my 2015 w/ 72,000 miles on it. My fronts are now leaking, but I caught it early. I just ordered new ones three days ago. (Arnott's from RockAuto). Hopefully you get your fixed before the compressor goes. I can offer a few more suggestions if you decide to tackle yourself. Just reply.

I have a 2013 Laramie and I can’t find the relay. Where is it typically located?

I don’t think you need nitrogen because the normal air we breath is 78% Nitrogen. My profession is an aircraft mechanic and been one for 47 years.

The compressor helps to push nitrogen/pressure back and forth from the shocks, in order to achieve proper ride height. Without tanks, the compressor would need to push out the full 175 (give or take) psi that the shocks require. By having pressurized tanks, the compressor only need to push the 10 to 20 psi (difference between tank and shock). As pointed out below, nitrogen is dry, so it prevents freezing. It's also a larger molecule, so less likely to leak. (Same reason some companies use for tires.)

2015. They all rust. Even the new ones 🤑😂😜

@@grizzlyfn393 oh well that’s great! I just paid over $30,000 for a 2018 rebel.

Let me know how you get on. You may have a leak.

No moisture in nitrogen

Rams don't use an oxygen air compressor. The system is nitrogen with holding tanks and a pump

I ask because mine went out. Tried to pull a trailer and said going 4 hi and wouldn't stop trying, then exceeded weight limit. Drove ok for a week then the back was hi front at exit entry. Local guy said drop it by the shop. Rear tire was low, like 29 so since he couldn't figure it out might as well air the tire up. The pump came on! He couldn't figure how the 2 were related but he found the intake hose to the compressor was crushed or collapsed. Air filter ok just collapsed tubing. Cut the tubing off and it worked again. So, maybe check to see if the compressor like and filter is good. If it can't suck in air the bags won't inflate and it will overheat and shut down. Think the hose cost like 40, could be DIY modified cheaper for those that want to save a buck.

yes for sure always when the bitter cold returns to canada dodge has no fix but dont buy 1 with an air ride system

now that it is warmer today no problems

@@jamesbork127 figured it out. 4 months prior had the bumper and tailgate fixed. Took to an old dodge guy. He took in shop and noticed tire pressure low so aired the rear right. He heard the compressor come on. He knew the compressor worked and began searching. Somehow, the inlet hose was collapsed so the compressor wasn't getting air and shut off for protection. Think a new $14 hose and all good. May e the repair guys crush/crimped the hose fixing the bumper
