Techstream may be useful - just ordered one - lowest price is 17 dollars on ebay.

You got me curious enough to peek under the wheel wells. Indeed, it is setup similar to the LX470 sensors with a sensor at the upper a-arm. A similar procedure should allow you do to an easy AHC leveling of the front end, or lift all around. - AHC Sensor Adjustment for Lift

And they look the same in the rear as well. I'm hoping to have some time tomorrow to mess with them a bit.

OK fellow LX'rs (we need a cool nickname). I Adjusted the sensor on each corner of the truck and achieved 1.25" of lift roughly. I measured each corner from the fender to the top of the rim. It measured 10" before and 11''1/8-1/4 after in the front and similar in the rear. It also helped to level the rake. Its now 11.25" +-1/8" all around. See Pics. Hope this helps! Its not a massive difference but for 10min in the driveway, i'll take it.

First pics are in H and second pics are in N
Last is in H

Nice! Wonder if that's enough to need an alignment.

Ive only been able to drive it around the corner a mile or two. I am going to have it checked but it isn't pulling or anything like that but we shall see.

This is in N....one more pic

How did you do it? Just by moving the sensor up the guide?

Let's is a write up @DeckerT4R !!!!!




Please......

The first picture is the front sensor stock
The second pic is how i moved it.

It was rather simple. I didn't even take the wheels off. I Set the system to High to give myself room.
I pressed the Off button on the AHC system so it didn't move and then turned the car off. The front sensors you slide all the way DOWN (see pics for reference). I didn't get a pic of the rear, but you do the OPPOSITE. You slide them all the way UP. the end.

@DeckerT4R You are the man! I know what I'm doing on Sunday before the Superbowl

Thanks @DeckerT4R !!!!!!!

Did you happen to Check your fluid levels before and after?

Yes, please let us know. I don't think it would pull either direction but you could eventually see tires wearing on the outside.

I didn't sorry

Good stuff!

Did you happen to get how much higher the "H" position is? Is it the same 1.25" higher? Wondering how much more droop is in the system in that mode.

The AHC still works exactly the same. It lifted everything equally. It's still 2" higher in H.

Nice. Please provide an update if you could after you get a chance to drive some more.

Is handling affected at all? Do you think you can squeeze 35s now or will it rub on some other part?

 

[Fasternfaster]

this is super interesting... I would like to see how things are when the system is in "low" mode, does it still go all the way down? it seems to me like the car is almost on the bump stops when it is in low, i have a bit of a step on my driveway and since i use the "easy access" mode backing up in the mornings, sometimes i hear a sound from the suspension, i wonder if its hitting the bump stop from going down the step. Also want to know if you have any rubbing issues in "Low" mode with those tires.

If you have Techstream, there is a "height offset adjustment" that lets you change the height that the computer considers to be "normal."

GSIC - Global Service Information Center

Adjusting the links on the sensors should also work. Note that after any height adjustments, Toyota recommends doing a zero point calibration to re-initialize the various sensors.

I am very thrilled to see this and dying to know how handling is affected.

I was looking at a second LC but may buy an LX if this works out.
