Im still looking for a solution to the rough ride. My suspension is nominal by all metrics, yet still harsher than it is supposed to be. New globes, new tires, most bushings, still harsher ride than my wifes RX. Ironically, the lX handles better: curves, turns, big undulations are dreamy in the LX. Little bumps come right through.
I keep coming back to being over sprung, but my pressures are right on per Techstream. I'd like to get true pressure readings from the hydraulics. That's my next diagnosic step, i think.
Recognize that the factory 'target' numbers are guidelines and not necessarily optimal for your unit at this time and state of wear.
You'll most likely need to play with the pressure settings front to rear in order to find the best setting/ride.
Stay after it.
