LX570 AHC Globe/Accumulator Replacement

[vwynn]

Outside of failure, Around what mileage do most LX owners start replacing or considering replacing their globes?

5-7 years.

Behind general maintenance, the purpose of the exercise was to just get everything leveled out. This is one of those situations where the phase "better is the enemy of good' comes into play. I'm going to get back on this tomorrow but need to get additional fluid.

put a floor jack under your breaker bar and put a little bit of upward pressure while you try to loosen the globe.

Or use the handle of the floorjack as an extension of the breaker bar…

The hexes have been known to round or snap off the globe. The floor jack trick helps prevent that failure mode… so you are more likely to get away with said breaker bar extension

'11 LX570 w/ 170K Miles.

I 'attempted' to change the globes today. Did my research and tried to follow the directions but things went south when I could not get ANY of the globes off. I had breaker bar but zero luck. Assuming they have been on there since the beginning of time. Rather than leaving it, I decided to refill it and get it back on the road. Fluid back in, started the bleed process, DF, PF, DR, PR. From What I could tell (note, first time bleeder here), I had fluid coming out on all corners and no air. Cycled through Low, High, Low but my ride height is all over place. As a result, the system is having trouble locking in on L, N, H.

Is this a sign that I need to re-bleed the system or that I may have overfilled or underfilled the reservoir? I say the last part because I can't see the min / max line, even with a flashlight, so I had to eyeball it based on fluid I took out.

Appreciate your assistance on diagnosing this. Thank you.

Grind the chamfer off a 13/16" socket and gently tap it on to the globes. My globes were quite rusty and a 24" breaker bar took them off relatively easily.

For the fluid level, go in under the truck from the rear, next to the spare tire. You will be able to see the rear of the fluid reservoir. Stick a flashlight up there, which will backlight the reservoir and allow you to see the fluid level from the access door in the wheel well.

AHC Globes changed, fluid flushed, and height leveled out at 35.5" (Ground to Fender) all around.

I just got my order in from Impex and was excited to get my AHC with 260K miles refreshed and smooth riding again. That is, until I discovered Impex had sent a wrong part #.
This is particularly disappointing since I ordered these a month ago, and they were delayed due to an out of stock item.

For those interested in the costs for ordering through Impex:
4 Globes at 91.24 each = $365
Shipping to AZ $107
Tarriffs $ 76
-----------------------------------
Total for me $548


Now to see what Impex will do for me... Tariff is non-refundable, hoping that I don't wind up paying more out of pocket!


The wrong globe is shown in the attached picture. It is 49151-60010 which is supposedly for the LX470. Interesting that it doesn't have the bolt head on the outside edge, but at the threaded mount surface.

Has anyone gone with aftermarket globes yet? eBay min pricing is $800 now. Amazon prime $279 for a full set aftermarket….. that’s significant !

It is significant, but they last at least 100k miles to spread out the cost, and this isn’t a part that a dozen companies have managed to build for 30 years without issue. You can’t even inspect the important parts for differences in build quality.

It’s your money, but I wouldn’t take the risk.

Understood. I’ll try to hunt a set for $500.

 

[AZLX570]

Isn't the labor and headache alone of having to possibly re-do it if they don't last worth $500?

Found a set for 580 shipped with best offer. Seems to be the best out there. $280 more (double) to go OEM is the right choice

OEM is generally ALWAYS the right choice for 200 parts.

Luckily I haven’t had to replace anything else substantial yet. Had the truck a little over a year now.

I just redid mine at 165K. Didn't do the analysis on if they were needed / not needed just felt like it was time. Globes from Japan for ~$600. Fluid was ~$150. My issue was getting the globes off on my DIY 'attempt.' The videos make it look easy, mine were not easy to remove.

 

[AZLX570]

Yeah an old bolt that's seized seems to give a lot of people problems. Or just rounding off the top

After helping 2 other houstonites with globe swaps, I just completed this on my own rig. While waiting for the parts to arrive, I pulled off my slee protection plates and flushed my fluid. swapping globes took 1hr including normal amount of distractions from kids. For anyone looking at this last page and hoping to avoid scanning the previous 34 pages, here's the rundown:
0) top off AHC fluid
1) attach 1/4" hose to bleed nipple and release all the pressure. rig will drop. leave bleeder open
2) using 13/16" socket and breaker bar, unscrew globe. fluid may still gush and spill when you unscrew.
3) screw in new globe and towque to 111ft/lbs
4) close bleeder screw
5) start rig and let ahc pump level out the rig. leave car on and close all doors
6) crack open bleeder screw (yes, while rig is on) and close after a few seconds. ahc pump will kick in as you're bleeding to replace all the fluid you just drained out. repeat until fluid comes out without air bubbles. only open 1/4 turn and fluid will slowly come out. opening more will let fluid out faster, but you'll see bubles in the hose because air is entering from around the bleeder screw.
7) shut off rig and top off fluid.
8) repeat.

Wondering why you top it off first? I’ve got to do a full fluid flush too and planned to drain it all out from the get go.
