2010 LX570 AHC lean, super bumpy ride, and other problems (1 Viewer)

[TexanLX570]

Well, the 2010 LX570 rides basically like new!

I changed out the 4 globes/accumulators and that fixed everything. The lean. The ridiculously bumpy ride. The extremely noticeable adjustments that used to go unnoticed it’s all much better. Well worth the time and $6k+ savings.

Accumulators cost $500 from Japan off of eBay and 2 2.5l of AHC fluid cost $100 off of Amazon.

Pretty easy job but the bleeding is a bit time consuming. I used 2 2.5l containers of AHC fluid. Bc I was flushing(Lexus dealership didn’t flush fluid when they changed two of my shocks recently. I didn’t request it) so I used every bit of fluid I had during bleeding. Turned car on after each accumulator bleed and let pump refill

I would’ve used another container of fluid, 3 total 2.5l, if I had it. Fluid is much clearer but not bright pink like new

13/16 socket worked great on accumulators

Also suggest for adding fluid to reservoir an at least 2’ skinny funnel. I wasted too much time trying to rig a transfer device with a brake bleeding pump that I wish I could get back

I took off the running board of one side. I wouldn’t do that again bc too time consuming but each time I went to that side I was thankful for all the room I had.

Anyway, thanks to everyone on this thread for all the help. I really needed it and made job a lot easier

Chainsaw was last resort?

Congrats and well done.

For the next guy, AHC leaks at the shocks is often a symptom of failed globes. Reason being is the hydraulic system no longer has working accumulators to absorb road imperfections and the resultant harsh ride - but this also dramatically spikes hydraulic pressures within the AHC system causing stress and leaks in the shock seals. Obviously if left long enough, that can permanently damage the shock seals, but its also very possible that fixing the accumulators first may be all that's needed.

I didn’t have a bumpy ride but that is what I thought at least. I had three struts leaking. So I had all four struts and mounts replaced as well accumulators replaced. Wow. Feels like a new lx.

I used dedicated Land Cruiser shop. They stated that one of the accumulators was bad thus the leaking struts.

Thank you so much for this post! For the past few weeks we've been feeling a bump/bounce coming from what feels like the right rear wheel. At first I thought it was because my BFG KO2s were worn (which they were) so we replaced those tires. Still felt the bump/bounce so we took it to the shop, our trusted tech was OOO, and later a new younger tech we'd never worked with called back and said "You need new brake pads." Nope, that's not it either. So we are thinking I might need to follow your lead here to get our LX back to tip top shape.
