Builds The Guzzler - 2009 LX570 (2 Viewers)

Great build! How has your AHC held up?

Why thanks! I’m just struggling along.

No issues with the AHC basics, it goes up and down adjusts damping and does its magic just fine. I have a bit of an uneven height issue on the right rear which persists beyond adjusting the offsets in tech steam and sensor lifting, so there is a zero point somewhere I can’t find or the ahc ecu doesn’t love me. It’s no more than the ‘cruiser lean’ and sometimes I’ll be flat as flat and the next day .75” out. It isn’t a problem, just a thing.

I don’t worry about getting stranded or anything, it always works fine. I imagine in a year or two I’ll replace the globes, they are only $150 each, and I think although fine, it’s a good 10 year maintenance item.

Previous owner had the ‘shocks’ replaced due to leaking, which is also normal.

In general the costs and maintenance schedule is in line with or less than a stock spring suspension, and WAY less than a lift and aftermarket setup.

I fit real 35s with only minor adjustments and minor rubbing, have a nuts on alignment with stock UCAs, and have 3” of on demand lift for messing about, while driving home at 80 with a 1” drop for better aero.

Thanks for the details. I can live vicariously thru those who modify LXs why my wife gets to mob around in ours hauling kids.

Drove around fidalgo island with the family today to celebrate 220,000 miles.

Fixed the snorkel whisper wind buffeting above 65mph. It wasn’t the snorkel at all, but the stock front load bar on the rack. Pushed it all the way back and no noise! Excellent. I’ll look later into how far forward I can bring the load bar and see if it is an interaction or just the load bar was in a resonant location. I rarely use the rack so it isn’t any big deal to me to have it back.

I can now recommend the generic snorkel kit I installed as an option if you like the look of the TJM airtec.

Good to hear! I’ve got one in hand and am hoping to have time to do the install in the coming weeks. Definitely going to be using your thread for tips.

Any advice you have before I start drilling some holes in my fender? Thanks!

If you can source threaded and barbed connectors for the air pumps it will be immensely easier to seal into the snorkel. Barbs for whatever hose and threaded into the snorkel inner fender.

I look forward to seeing what you use for the air box seal.

Started a five tire rotation today. Wanted to put some beads in the tire the garage had some trouble balancing.

No problem breaking the bead on the backside and adding the beads in, but it took a bit of finagling to get the bead to seat and hold air. Never tried a backside seal before.

These 275/80r18 lt tires a pita to work with manually.

I got that one tire swapped with the spare., just three more to go.

Decided I’d start getting the items together for the accumulator replacement. Just ordered the globes. My fluid is pretty new, so I will plan to filter and reuse it, probably get a few liters just in case. Haven’t seen too many replacements done on the LX570 yet, but I’ve decided that the ride has actually decreased enough in quality to do this.

I’m at 222000 miles with the only ahc service recorded as shock tubes replaced at around 120,000. I think 10 years and 222k is pretty good service life for the globes.

Do us all a favor and document/photograph it for us!

@ToyotaIsLife can you confirm if the 17x7j steel rims clear the 200 series brake rotors? I’m looking at part number 42611-60A61. And same q on the 17x8j steel rims? I think they will but don’t want to burn $750 finding out they won’t. TIA.

*Yes they do 100%.

Direct fit.

That is the main reason on why it is the most popular wheel here in qatar. It fits nicely and has a very negative offset (inside the fender).


(This is my rig with an oversized(bigger than the normal balloon tires. )

(FULL BUMP/FULL COMPRESSION, no rubbing)

Just read this and having the same issue recently. From the ground to wheel well mine is always .25-.5 inches different and can't get it to be perfect no matter what. If I measure from the top of the tire all sides appear to be exactly the same. Haven't been able to figure out why it won't level perfectly, but it's not really noticeable just an annoyance. Mine is at 150k miles and still working well otherwise.

Perfect. Thanks. Do you have any info on the offset? I haven't been Able to find info on that, was figuring it was around 50mm

Oh I have a difference fender to top of tire. Today it's flat all around and the ride was markedly improved. I think that my passenger rear is messed up somewhere, we've had a weather change (more humid) and now it's leveling, I may need a new position sensor. Makes sense it would ride rough if the shock is fully extended.....

Accumulators / Globes in the house. They are marked correctly on the boxes, and look correct inside the boxes. Heavier than I would have thought. International delivery took three working days. Incredible.

 

[grinchy]

There are an additional six accumulators on the LX570 beyond what I sourced above. There are a total of three each side in the front, and two each side in the back.
Here's the part numbers
Front (per side)
49041-60030 Accumulator sub-assembly, front suspension control No. 1
49147-60010 Accumulator front suspension control No. 2
49141-60020 Accumulator front suspension control

Rear (per side)
49158-60010 Accumulator rear suspension control No. 3
49151-60020 Accumulator rear suspension control

I'm in $600 on the four 60020 parts, so I'll roll those and see how it goes.

Also for those installing at home, make sure to pick up four 49156-60030 Suspension control back-up ring. each install takes two o-rings, and the 60020s come with one. At least mine did.

Torque on the 60020s is 111 ft lb. Use the bolt head which is on the top of the accumulator.

 

[grinchy]

Here's how the three front work:
Number 1 and Number 2 are 'High gas spring'. Globe is 'Low gas spring'.

Proper disposal is important for pressurized parts, right?
Also, this show exactly where the pressurized portions are in each accumulator, from which one can deduce some stuff about general design, pressurized volume etc and so forth.
