Mud, I recently removed the accumulators on my '99 LX to make room for Metal Tech Land Cruiser Sliders. The top bolts on the accumulator assemblies were damn near impossible to get to and even when I got the wrench on I may have gotten 1/16 of a turn on the bolt head. I ended up removing the...

Hi All, Just bought a 1999 Lexus LX470 today (180k miles). Drove quite smoothly for 20 highway miles after filling the tank to full (87 from sams club). After parking at home, I noticed white smoke coming from rear driver side wheel. Liquid was also leaking on this side. The whole torsion bar...

Does anyone have a good number for the AHC suspension cylinder bore diameter for the UZJ100 with AHC models, and for bonus points, the HDJ100 (diesel) models with AHC? Anyone know if the diesel AHC system is the same or different? As in, are the target pressures any different than the petrol...

TL;DR - I believe my front left suspension damper is stuck at the stiffest setting, causing bad ride quality. This is my first post here, and I'm only posting because I think I've read every AHC thread there is. I have a 2000 LX470 with 145,000 miles, and I'm trying to troubleshoot terrible...

After a year long search having sold my LXs, I was able to secure my unicorn 100 series non-nav AHC 2006 Land Cruiser with 59k miles in black and gray with gray interior, all thanks to @GTS550 who originally posting the ad! I had it under contract within 2 hours of the listing. The truck came...

So I finally bought a 2005 LX470, really wanted a land cruiser but they are a lot more expensive. Anyway, I didn't want the AHC suspension but now that I have the LX I want a way to keep in in High if I want to. Researched and all I found was a Slee over ride switch which they no longer make. I...

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...

This may as well be titled "The LX that 'Mud Built" because without the Mud community support of YotaMD this would not exist. So I offer an upfront and sincere "Thank You!" to you awesome folks that support your community vendors like YotaMD. Now, let's dive into the fun stuff. 2006 LX470 in...

Hi there, I have a 2008 LC200 and I am planning to prepare it for overlanding trips. I am considering adding Front and Rear ARB Bars (70 and 90 Kgs respectively) + Roof Tent (approx 80 Kgs) + Auxiliary LRA Fuel Tank (another 100kgs when filled). My LC200 is equipped with AHC (2'' sensor lift...

I fired up the truck in 30F weather and the "Check 4-Wheel AHC System" warning displayed. The warning has not re-appeared after multiple subsequent starts. I'm hesitant to ask this question as there may be too many possibilities, but is there a "common" thing I should check? At this point...

Turned right into a parking lot today and the front right suspension got stuck in the low position. Other 3 corners look to be in high mode. I parked and tried to lower/raise the suspension, but doesn’t move (light just blinks). The VSC is also stuck in the off position. Anyone have any ideas...

New to the forum and looking to tap into all of your generous advice and expertise! I’ve got a 2006 Land Cruiser with 112K miles on it, purchased in 2013. Vehicle has been great except for AHC issues. Took it down to Ecuador with me for a few years and in 2015 the front end just dropped when...

New owner here and trying to do preventive maintenance of the AHC To lengthen lifespan. It’s an 06 with ~140k miles on it so hopeful that by doing all this I can get a few more years out of it before maybe deleting. I did the fluid flush and have the torsion bars ready to turn, but the front and...

Hey! So I just picked up my (new to me) '99 LX470 with 167,000 miles a few days ago. When I did the test drive everything on the AHC seemed to work fine, but i'm starting to notice some irregularities with it and after much reading I'm thinking it has to do with the pump but not totally sure...

I have a 2006 Lx470 with over 250k that seems to have everything breaking in it! The steering column and rack are worn out and need replacing, the A/C compressor just blew out, and the center locking diff locked up on it's own when my wife was driving it. She drove all day long on the...

2006 LX470. AHC seems to work, it will go into H and back into N but won't stay. It even reverts during the same trip. If I stop for 5 minutes it's back in N. I know, there are a ton of threads on AHC but I don't have time to sift through them all to find answers. This is my first 100 and...

Hi all. I am new to the forums and just want to fix my moms car. I have an 2002 LX470 that the PS shock went out. Is there anyone that has the FSM sections (Scanned or a pdf somewhere) for the replacing the shock and then bleeding the system? I saw PADDOS post on bleeding the system, will it...

Graduation test shows only 8 bars, the fluid has 20k miles on it, rear springs are OEM from 1999 and torsion bars have never been cranked. The ride has been getting significantly harsher in the last 15k miles and I have No leaks anywhere on the system (struts, accumulators and globes, pump)...

I would like to check front and rear AHC pressures with a scanner and without the complications of attaching pressure gauges anywhere. First, I need to discover whether my Australia-delivered June 2006 Landcruiser 100 Sahara (similar to VX) with 1HD-FTE six cylinder 4.2 litre turbodiesel and...

Hi guys! I have a 2001 VX100 1HD-FT diesel with 300,000 miles on it. I've owned it for two years and love the comforts over the HJ61 it replaced. But the AHC is acting up! I don't want to go conventional, I want to keep the AHC. AFAIK everything except height sensors are original, and I know...
