IMO. Dont blow off bleeding the 5th.

I didn't find out there was a 5th one until months later. I'm thinking that would have helped my cause when it vacuum locked during the 4 globe swap. I couldn't get anything to bleed for awhile.

That accumulator isn’t part of the system except when lifting, otherwise it’s closed off and would have no effect on the rest of the system. If you bled it, you’d just be draining that accumulator, and nothing else would change.

Thanks for clarity on that.

Getting mine in today. So far have it bled and the front left accumulator replaced.
The back up washer is a pain to get in behind the seal. I ended up prying the seal out with a plastic cell phone pry then putting in the backup washer and pressing the seal back into the remaining gap. Took a few min to figure out.
The old accumulator definitely has both parts in it.

This is on my list. I don't understand what the 'backup washer' is. is it included with the accumulators or do I need to order separately? Thank you.

@skymast. It looks like it comes with it. I purchased globes from jdm-planet.com
 
Thank you guys. I assumed but always better to confirm!

No. The earlier made globes had a bigger gap and required the o-rings to close that gap.

Nope. I couldn’t even fit them on my globes near the o rings. No room.

Makes sense. I was concerned because "backup ring" is suddenly making sense, those are often used to get an elastomer o-ring to hold up to high-pressures. But if there's no room, no choice.
 
OK I just did my globes today.

As I was finishing up I put it in “high” refilled the reservoir. Then bled at each corner until the air bubble were gone.…

But now it won’t go back into normal or high and says I have an error..

Any suggestions? Previously read if I immediately put it into high when I started it I could get past the error. But that’s not working… open to suggestions!

sit in the truck with it off. Close all the doors. Start it, and as soon as you start it continuously keep flipping the switch to the High position over and over until it shows the flashing message indicating it is rising up. When that happens stop flipping the switch and just let the truck idle and continue running for 5-10 minutes. Then drive it around and come back, and cycle through L/N/H a few times.

Welllllll…. It never show it was changing and then it registered that is was “in” high and started to pressurize.

Thanks! Seems to be working…. Its idling now and I’m going to drive around here shortly.

I’ll report back, but I REALLY appreciate the advice 🙏

Awesome! Make sure to leave the doors closed while it's idling so that AHC continues to function. As soon as you have a door or the trunk open it'll "pause".

Worth noting that that process you described worked, but a couple of little differences.

My dash never showed it was going into high it just suddenly showed high and then started going into high very slowly.

My AHC seem to be stuck in the off position but didn’t show off until I restarted. Once I did I could see the “off” and let me turn it back on, then the system let me go into high.

I’m still troubleshooting a little bit. I can’t switch back into normal height with the control, but if I drive 20 miles an hour it’ll automatically go back to normal. So at least that functions. Also keep getting an error on my dash.

I’m kind of tempted to bleed the system some more but I’m afraid if I bleed it and goes into low I may not be able to get it back to normal again.

Weird stuff.
