2014 1500 Air Suspension issues

[JLayne105]

I know this has been discussed, and I have done some browsing but wanted to share my experience and ask for some help before I start shotgunning parts at this thing. I have a 2014 1500 Limited with OEM air suspension.

The rear drivers side of my truck started intermittently sagging to bump stop. Sometimes once the truck was started it would raise back up, other times not. Occasionally it'll be sitting normal height and while driving it'll end up getting back to bump stop, causing an incredibly rough ride. I thought the bag was likely the culprit but then after putting the truck into tire jack mode and lifting the rear to change my brakes, the driver side rear wheel (while being sagged) lifted straight up still sitting against the bump stop as soon as I began jacking. As if the air shock is not functioning properly at all. If it were functioning properly, or even if the bag was leaking, I would expect the wheel to sag a bit as the truck was being jacked up, as a normal suspension does, correct? Seems all other corners acted this way.

This leads me to believe I have a faulty valve block. Any insights?

You're probably at the point do you want to go down the rabbit hole of fixing the air suspension system or just delete the air suspension and go with a conventional suspension.
You can use AlfaOBD to attempt to troubleshoot the air suspension, it could be height sensors, valve block or combination of.
There's a bunch of pre-packaged kits to delete the air suspension or with a little research build up your own.

Tough to say, as mentioned...AlphaOBD is a great tool to help trouble shoot the issue. Also if you choose to delete the air suspension you can use AlphaOBD to get rid of error codes you would get from deleting it. We have had many customers have OEM air suspension issues and decide to delete it and go to a traditional suspension. If this is something you would be interested in, send me a message and we can discuss a package and pricing

Another vote to remove the air-ride. Considering the age, you will begin chasing problem after problem. Could be switch block, but also could simply be a single fitting's o-ring. I chased and repaired many of these issues for months before deciding to go conventional, then a few months later did a 6". Should have removed air-ride YEARS ago!

I’ve actually fixed my air suspension system, fairly easy and not too expensive. I replaced the pump in the back airbags for about $300 and it was very easy. The problem was my rear bags for cracked due to age rubber cracks with time so I had a whole bunch of pinholes so I ended up replacing both of them and because of that my pump got overworked and it burned out so I replaced it. You just have to go into Alpha OBD and set up the parameters, but it’s very easy.
