I've been lurking here for a while, figured I'd say hello.
I picked up a totally rust-free '06 LX470 with 123k miles a few weeks back. This is the 2nd car I've ever owned, and the first since I moved to NYC 12yrs ago.

I don't know the first thing about cars and so have found this place completely invaluable. First order of business was to remove the running boards, which was fairly easy.
I then almost immediately accidentally drained the transmission, confusing the transmission drain plug for the engine oil drain plug... the mechanic had a good laugh about that as he pumped new fluid back in.

Then it was time to actually change the oil+filter, replace some weak hood-struts, and rust-coat the underside in preparation for NYC winters.
Today I flushed the AHC fluid and replaced all four globes, all of which were original from '05, two of which failed a pencil-test.
The fluid came out brown and frothy as expected. I felt an instant improvement in the ride with new fluid+globes. Tomorrow I'll grease the driveshaft. What next?

I'm feeling good and wanted to say thank you for the many many helpful threads here.
I don't have any real questions yet but I'm sure I'll have one tomorrow or the next day. Cheers!

And make sure the spark plugs are tight and not backing out. Seriously.

And while you're at it, inspect the rubber boot ends of the coils on each spark plug for cracking, replace if in poor shape.

Hi all,

A week or so ago I replaced the globes+fluid on my '06 LX470. After replacing the globes I mistimed a reservoir refill, the tank drew down to empty, and the AHC switched itself "OFF". I topped up, restarted the car, and was pleased to find that fluid drew down into the system, the car equalized, and I could move between L/N/H with ease — and I had 12 gradations on the side! The ride was much smoother, and I figured all was good to go.

However, over the next few days I found I had trouble moving through L/N/H — it would take a very long time to do anything. Eventually I landed back at N, and now if I try to raise or lower, the light will flash forever, and the car will not raise/lower. I can (sometimes) hear a stuttering sound, not from the pump but more from under the car.

I ran techstream to take a look and was not able to engage the motor/pump – it would switch to OFF and stay there. I had error code, C1763 - "Oil pressure for pump motor abnormal." Cleared that, tried to engage again, same thing. The code didn't reappear but I'm still unable to engage anything. All of my pressure values were flat 0.0, too.

I'm sure there's air trapped somewhere. I want to bleed the system, but am afraid that I'll drain down to L and then the pump will continue not to engage, and I'll be stuck down there.
From reading around I also suspect my pump attenuator might have the suspected air, and I'll need to bleed that... but I can't find a clear description of how to do this.

Any ideas here?

Quoting here incase any of you guys have any ideas... having issues with my AHC raise/lower after globe replacement.

I also have poor ride and slow raise/lowering after globe replacement, along with c1762. Reading here points me toward bleeding the attenuator- Im going to try cracking each line at the attenuator briefly WHILE the pump is running. Anybody have experience chasing air high up in the system?

Hey-where did you get the globes from?
