LX470 AHC Suspension
My 2000 LX470 got 4 accumulators replaced by Lexus dealership when only 50K miles. The repair costed me $3500. The tech insisted that 4 accumulators must be replaced eventhough only front two went bad. A year and half late, I had to go back to the Lexus dealership to get front two accumulators replaced because they failed to work again. I wrote to Toyota to tell them the design of AHC is not mature enough to put on the market. They like the brake and need change very often. Now my rear accumulators are causing bouncy and need new accumulator. I drive LX470 and other SUV. I don't feel much difference between with AHC and without AHC. Therefore, Toyota needs to put new tech only the tech is mature enough. Also in the manual Lexus never detail how can you lower your car in order to get in lower garage door and should you raise it after into the garage and/or you can leave the car in low level. I left my car in garage in lower position for a couple month. It migh be the cause of AHC fail too soon, only 50K mile. I check the manual and book never mention if you can park your car in lower lever for a long period of time.

I bought a set to replace the factory accumulators from active suspension. My suspension guy said they are heavier and a little bigger. They shipped fast and total outlay was only about $1,700, so far so good, but they don't have many miles on them - I will say they appeared to be substantial units. http://www.activesuspensionsystems.com/

We have a 2003 LX470 with 34,890 miles on it. We bought the car with 14,998 miles in Nov. 2007. In Oct. of 2007 the previous owner had a problem with a bouncy ride and the car lowering itself and then raising itself back up. The Lexus dealer in Reno replace the accumulators and flushed the system saying that the AHC fluid was contaminated. Now we are having the same problem. The Lexus dealer in Reno told us that the accumulators were flat and the problem was contaminated AHC fluid. Has anyone had this problem and is there a way to get the "contaminated fluid" out? Any help would be appreciated because all the dealer can say is " That will be $3400.00 and there is no guarentee that it won't happen again in 2 yrs" Love the car but wonder how many other people are having this problem.

Wanted BAD AHC Acumilators
We are looking for bad or blown out suspension accumulators off all LX-470 models. We currently are doing a study on this system. We are hoping to design better aftermarket accumulators for this model. We are paying $100.00 each for bad units at this time. We are only buying a certain # of cores for research so please hurry if you are interested. Please send me an e-mail at adam@arnottinc.com if you have any bad units you would like to sell. We also pay for shipping charges too.
Thanks
Adam

I have a 2003 Lx 470 with the same identical issue. Two weeks back I took the lexus back to the dealer. They had to replace both front accumulators and shocks. Also replaced the AHC fluids.
Truck has done only 39k miles.
It runs much better now.

I bought the dealer warrenty with the truck, so didn't cost me a dime.
I was suppriced when they didn't charge me for the shocks since it is not covered under the warranty.

My 2001 lx470 is bouncy. The dealer wants to charge me $3700 to replace the "dampener(s)"...accumulators? After which, they still won't be able to guarantee it will resolve the suspension problem. I'm going to take it to a local mechanic who works on Lexus vehicles for a second opinion and estimate. Does anyone know if their is a reliable and less expensive route?

Have you done this conversion? Do you know the aproximate cost of doing it? I think for now I can get away with just changing the front struts OEM but in the long run I think front and backk suspension will have to go. The air adjustment thing is just too much trouble and expensive.
If anybody has experience with this please chime in.
