Any 4.8is air suspension experts in South Florida?

nagging issues with 2 4.8is's that I have. Replaced everything, still having ride height issues and error messages. Would love to find someone that is a "specialist" with these cars. Any rec's? Thanks.

Air ride is a pain in the ass. Swap to coils if you do not have and do not want to deal with Inpa every time something happens.

What have you replaced anyway?

Arnott Air suspension is located in Central FL around Titusville Beach. Of course, they are not likely in the business you need specifically, but they may have a lead on a place nearby you both.

replaced both front struts with new arnott struts, and new arnott rear airbags. A new ride height sensor, replaced ride height module, and air valve body. Also verified pump is working.

Did this on both 4.8is -
Black one sits a bit low all around, but not slammed like it was before and displays ride height error

Blue one sits abnormally high in the rear and displays a ride height error.

You need to adjust heights with Inpa or DIS. I find Inpa easier. Why replace the ride height module?

it was reading one sensor way out of range, even after replacing the actual sensor with a verified working one.

Transportador will hook you up...

On a laptop running INPA and DIS if you are willing to dive into your ECU. I had self-level-suspension inactive and my first success with the software was to reset that code after doing compressor rebuild kit. No problems since and I've put on 300mi. If you have TWO of these beasts - I think you would get a lot of value out of INPA access.

have inpa and pa soft... luckily i have two 4.8is trucks here with different problems. was able to diagnose it quickly once i figured out how it works. One needed a new EHC module. After that didnt fix the issue, I was stumped. I confirmed that the pump was working, but apparently, not strong enough.

Just a heads up, even if the pump is putting out 10 bar of pressure, it still might not be strong enough to make the system work properly. Swapped the pump and system now works perfectly. Now on to the second car!! lol

Anyone parting out a car with 2axle air suspension?

You might want to check the offsets via INPA. If they are out of range (circled in red) then it won't play and setup crashes every time the car is taken across an out of level surface eg angled up a kerb.... also, assuming you've reset the ride heights?

this has been one of my issues... one wheel shows like a -27000 deviation. I got that to calibrate the counts so all 4 wheels are similar, but when I rock the car back and forth to see movement, I only see movement on the rear two wheels. I have checked both front sensors and INPA does see voltage, but it does not show movement when the car is rocked back and forth. I assumed this is due to a faulty EHC module. I rebuilt the pump on this car and the pump is now working like new (as opposed to how slow it was before). It would get extremely slow by 10bar and overheat by 11 bar. Now it hits 15.5bar with no issue and is still below temp.

now just trying to figure out why the car wont sit correctly. Installed a known good used strut for the front driver side and a new arnott unit in passenger front. Verified both front level sensors work, but still no movement on front axle when I rock the car. I have access to 2 ehc modules of unknown health that I can swap. #1 shows no movement on either front sensor, #2 shows no movement on left front only. Any ideas?
