I was comparing the LX AHC springs that luckily weren't available when I needed them to the 06/07 Land Cruiser AHC springs that I purchased instead. It was actually on this thread that someone said the RH Landcruiser AHC springs were used in Australian 100's that came equipped 2 gas tanks, hence the assumption of a a higher spring rate. Below are the part numbers I was referring to.I do not see a difference in part numbers between an 06 LX and my random search of an 03 LX.
I was expecting the pressure to drop more than it did. I will perform the flush and see what that changes.
Since the springs vary pressure and I am stock with new OEM springs, then I really should not be looking at this with a magnifying glass. I think it's very close to how it would have been when it first rolled off the floor.
Also, the verbiage in the FSM makes me think there is % error in reading when using the "hand-held tester" compared to the gauge. "The cylinder pressure read by the Lexus hand-held tester is estimated by the pump emitted pressure so the pressure is approximately 1.2MPa higher..." This may be the reason why results vary between vehicles and users. I would be curious to compare results with the LSPV gauge (SST) since it would be live pressure and not estimated. Anyone have one of these tools?

I agree with you saying you shouldn't have to deal with this since you are replacing old with new oem, but unfortunately that's not the case with some people of us. Some here are in spec with the temp sensor unplugged on 15-20 year old springs, it looks like both of us were in the opposite camp. Have you gone through the thread:
My nagging "issue" with AHC is wondering if the suspension doesn't feel quite right. I feel bumps pretty well and I subjectively recall an older 100 series land cruiser standard suspension feeling like being on a cloud vs the small cracks in the road. The question is driving me insane when I'm...
I learned a lot reading through that whole thread, if you need cliff notes version of it, you can look at this thread:
I initially put this in the Definitive list of AHC maintenance items thread, but at almost 800 posts long and growing, it's going to get buried and the thread itself is very unwieldy. In an attempt to make as focused a summary as possible, I present "The ABCs of AHC." It's intended as a...
