Anyone know the shelf life of unopened AHC Fluid? My 2004 needs a refresh and this is 3 years old.

Hello, I have a tried the AHC sensor lift method, and followed the videos and write ups on here. I did not gain any lift. My truck AHC system works with no issues. Just need help or advise with the AHC sensor lift please. Please advise. Thanks

Looking for a front shock from a 1998-2007 Lexus LX470 or Land Cruiser with AHC. I'm working on something cool and need one for measurements. Located in Atlanta

Hi There, I have a 98 Model Lx470, which i have recently acquired, the car is mechanically fine and I have done the T.Belt and waterpump changes and the engine runs good TBH. The issue is that the car is missing the AHC shocks and Accumulator globes but all other systems seem to be intact...

Hi, I recently purchased an 07 Land Cruiser. Has a pretty bouncy ride so I checked the fluid which the reservoir is totally empty. Overnight the front suspension also tends to sit low. Also, the height adjustment button is able to raise the truck, but when I try to go from H to N or N to L the...

Haven't been on the forum in a while but after an exhaustive search for a LC 200 I recently picked up what I thought was a unicorn find. A 2008 LX 570, one owner, no accidents, lifetime Dallas car, 100% serviced at the Lexus dealership with all service records and 125k on the ODO - $23k. Had...

After cutting out the OEM shocks, then removing the stock springs I can't now get the replacement springs to fit. I have removed the rear drop links, disconnected the rear sway bar but still can't get enough room to install the new rear springs. I am going stock 105 rear springs with no lift...

I replaced my accumulators tonight but missed the step about having to have the system in LOW mode before starting. I drained and replaced the accumulators in NORMAL mode. Now when I start the truck it flashes N then says Low and gives the Check 4 Wheel AHC system. The pump won't run. I've tried...

Hi Folks, I picked up an LX470 earlier this year, and was jacking up the front to remove the wheel. I noticed that my passenger wheel was off the ground, but the driver side was still planted. I am still running factory AHC without any issues. I did not measure it, but I would say the...

I was just driving on the highway for 8+ hours when all of a sudden my truck started pogo-stick-ing up and down at every slight bump in the road. I thought maybe i had hit a bad stretch of road, but no other cars around me seemed to be bobbing up and down like me so i kept driving another 5 min...

Looking for rear shock for LX470

Hi all. New to this world but loving the info that’s been shared around. I’ve been reading heaps of threads about AHC as it new to me. Driving 1998 100 Series VX Limited. Original globes (dated 1998 on stickers) and unknown when last AHC flush occurred. First thing I did was got myself a...

I just pulled out my fully-functional AHC system to move over to traditional shocks. These are off of a southern truck with little to no rust - 2004 w/ 250k miles. Here's what's available & prices: ACH Control Module 8929060040 - $125 AHC Pump Assembly 4891060012 - $300 AHC Valve Block...

So I've had my LX470 for about 8 years now, and the AHC has worked great up until now, with little maintenance. However, in the last year it has decided it doesn't want to go into high mode anymore, and even going from low to normal is a gamble. Finally, a few days ago, the AHC OFF light came...

I've been trying to figure out the source of a clack/clunk/rattle that is getting worse and occurs when I drive over rough road at low speeds. I've scoured Mud for leads and gotten some good feedback on one of my prior posts on this issue. I took it to a new garage to get a fresh perspective...

2004 lx470 stock AHC Found a killer deal on 285/70r18’s Will the fit at stock height!

I’m buying some globes from Japan because someone recommended I should replace them on my high mileage 06 LX. My question is, would it be better to just get the globe or is there any reason to get the whole accumulator assembly which is part 49051-60020 and 49052-60020 for right and left sides...

If i read AHC neutral pressure for LC 100 under these two conditions, which one will report higher REAR pressure, and why? 1. Fuel tank full and all seats installed, including third row. I know this is recommended. 2. Fuel tank a quarter full and third row seats removed. In both cases, there...

I'm currently running the King 79s. She's a heavy girl. I have: Front and rear steel bumpers Winch Rear tire carrier Rear swingout Full drawer system Heavy roof tent 8 Gallon water tank Solar panels ...and more stuff I'm not thinking of Front pressures are dialed in using the stock LX...

Hello all, I've done a forum search on this topic, naturally there is. ton of chatter on this, however in my search I can't seem to find an actual step by step guide on how to do this myself on my 2008 LX that is detailed enough to cover the process fully from start to finish... If there is one...
