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.
 
Did you install the accumulators in the correct positions? I believe there are front and rear specific accumulators (high and low pressure).

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
