So i have a 2013 lexus LX570, its got over 190k miles and ive owned it since it had 0 miles on it, recently the AHC pump went out so i replaced the pump, the shocks and struts, and the globes all at the same time all are oem toyota/lexus parts, ive made sure to bleed the system at all four corners AND the 5th accumulator and i can confirm there is no air left in the system, the car will go to the high position, normal and low position with no problems, HOWEVER only the front end seems to be working properly in the sense that it actually absorbs shock and articulates correctly but the rear end does not seem to absorb any shock and it constantly wants to ride super harsh and bouncy to a point i can barely keep the car on the road, i did make sure to rebleed everything and i also made sure my height sensors were working and that they were calibrated correctly, my fluid is clean and free of air but i still cant figure out the problem, ANY AND ALL HELP IS WELCOME

Not being a smart ass did you install anything backwards? When doing projects like this I have always noticed its a small stupid detail so easily overlooked, because we are trying to look at too big of a picture.

I originally thought i did have something backwards cause i agree its usually something small and stupid but i can confirm nothing is installed backwards
Do u have techstream or at least an OBD2 reader? Seeing AHC pressures and valve data (or possible codes)when truck is running might give you some clues.
I know I did some maintenance and forgot to plug in two of the rear plugs for the AHC/AVS and the truck didn't show any dash lights but was riding strange and showed codes when I scanned it.

I dont have tech stream but i am able to get all the live data and info i "should" need from my autel maxisys ultra S2. I say "should" because i have tried to get a version of tech stream working on my laptop but from what i have seen and read it doesnt give any more info/live data than i already have, im currently waiting on some new accumulators, i know its uncommon but i cant tell you how many times i have gotten bad parts befote
