Looking for a little help with my ahc system in my lx470.
I have noticed the LX sitting low in the front. my ahc system seems to work fine going from N to L and H But the ride is alittle rough.
a few weeks ago i the a system flush and the old fluid was brown and murky. My Gradations are on the low side as well 7 or 9 as far as i can remember.
I ran techstream last night and four the presser high in the frontand that i also have DTC Code C1762. I am mainly asking is i need to buy new globes or if there is some other fix i don't know about

Thank you for any help.

I am curious about this as well. I to have noticed that my ride has gotten a little rougher. I changed my AHC fluid last summer. I also had code C1762.

Crank torsion bars up to relieve pressure up front.

For both you and @Reckthor , I suspect you have a leaking globe (or multiple) and the gas from the globes is causing issues with the pump (and therefore the 1762 code which means that the pump isn't building pressure as fast as expected). That's common with blown globes that releasing gas into the fluid. It also feels harsher because the gas is preventing the very incompressible hydraulic fluid from doing its thing.

Easy fix. New globes, flush, check pressures, adjust torsion bars. Done.

Note: strain any fluid from plastic bottles before putting it into the system. There were bad bottles in ~2020 and the following year(s).
 
@suprarx7nut Thank you for the information I just bought 4 new OEM globes.
Should I wait to adjust the torsion bars until I install the new globes? They are coming from Japan so I have 3 weeks to a month wait.
I also forgot to add that i Have a slight weep from my front passenger "shock" Could that be from being over pressure?

Don't wait. The globes have nothing to do with neutral pressures. Go ahead and adjust now.

That seepage is what I'd consider "OK". Dripping wet is not good. Moist oily residue can be fine.
