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

Did you tighten the suspension with the truck in the ground? If tightened while on a lift the bushings may bind.

Yeah i made sure of that, ive been wrenching for the better part of 5 years now with multiple certifications, i feel like my problem has to be something simple that im over looking but not quite as simple as binding bushings
Maybe the new rear struts are air locked or there’s a tab in them that is preventing fluid circulation
