I replaced my globes and have bled the 5 accumulators many times and in the correct order It is bouncy as hell like a basketball now. Before it was just rock hard stiff. AI says all signs point towards me having to replace the center accumulator also called the Control Pump Accumulator. Can this be my main issue? Have anyone ever swapped in a new one and is there tips or videos on it. I have a new lexus one coming. 2006 LX470. The lo, normal and hi raises and lowers perfect, and the vehicle still as it should front to back and side to side. It is just bouncy at low speeds, small bumps. Any help would be apprciated

What are your pressures?

No access techstream, so im flying blind unfortunetly

Also not much fluid change when raising and lowering. it raises and lowers great, but fluid change in only a few bars.
You're not going to get anywhere without being able to read your pressures. Lots of tools can do it for you. I went with the obdmx
Where did you buy the globes from?

unfortunetly I cheaped out and got aftermarket ones. I know, thats a big fail. The center accumulator is OEM, but not on yet.
That may be your issue. Order from Impex to avoid dealership prices.
Yikes, I was wondering what could possibly be the issue after new fluid, new accumulators, and working pump. Then I read about the aftermarket accumulators, should have mentioned that from the beginning. That is most likely the issue. The nitrogen pressure inside those globes is probably not the same as OEM and the rubber bladders are probably different as well. The accumulators are under tremendous pressure, not something you want to cheap out on.
This is what mine shows. Of course there are more fields to choose from but I believe these are the relevant ones.
It's probably full of air still. After I did my globes I had a poor ride and bleeding didn't fix it. I started parking it in L for an hour then raising to H for another hour and then going back to L. Again just leaving it parked but changing the height up and down over the course of a day. After that it was much better.
Someone on here recommended that method because it allows fluids to exchange between the lines that are under high pressure and the reservoir which is only at atmospheric pressure. The lower pressure allows the nitrogen gas to dissipate out of the fluid much faster.
Pressures look ok. Accumulator is reaching 10.4 which is max pressure so that doesn't seem to be the problem.

Those pressures are mine, not OP's. Screenshot provided as an example of what he can expect from a tool like OBDMX. But yeah, thanks I think the numbers look good too. I've been working on it. Bleed, cross level, cranked the bars up 4 or 5 turns. My initial readings before the work were 7.9 front, 7.5 rear & 10.5 accumulator. Temp sensor NOT disconnected.
Also I agree with your point about changing the height a few times. My initial drive after the bleed was unexpectedly harsh. After messing with the bars and leaving it in various heights over the last few days it has smoothed out a bit. I only have 7 grads (up from 5) so I do still need to replace the globes. They are over 25 years old, so it's time.

I may bite the bullet and go buy OEM, but all signs also show a bad center accumulator too. Will pressure readings confirm that?
ty!ill keep trying that
The computer would also read the pressure of that accumulator as well go into the very long, HC thread, and that will list all your pressures and the order in which to adjust your height sensors and torsion bars. If you can’t get it in spec, that’s when you would look into Springs or the fact that you have aftermarket accumulators. This system is very easy once you conceptually understand the process of adjustment.
