I have written posts before but I seem to still be having problems with my suspension, car rides badly, tire pressure is good. I took the car to Lexus just waiting to hear the laundry list of issues with the car only to be dumbfounded hearing that everything is good. When they told me this I started thinking WTF, it's an 8 year old car with 155k on the clock, the shocks or something has to be bad, and Lexus ALWAYS wants your money, but they said it's fine... SOMEBODY HELP I don't know what to do anymore.

 

Your shocks are original thru are toast. May not be leaking but they long ago started not working as intended. No matter how they look. Even at 80k they are mere shadows of what they used to be.

 

My vote is shocks as well.

The problem with diagnosing shocks/struts is they don't always fail completely. So mechanically, they are working but are not giving the sort of ride that it was designed to.

I know my GX at about 100k miles just had this sort of harshness that was tough to put your finger on. New shocks and struts made a big difference.

 

Mine were leaking like nobody's business at 90k miles and drive was day and night after replacement at 155k miles they must be in bad bad shape.
