LX570 AHC “Basics” - Added as sticky thread for AHC Issues

[sticky iqqy iqqy]

You won't lose much fluid at all if you just disconnect the hoses to add the spacers (especially if you already have the truck in Lo before removing the wheels and allowing full suspension droop). The issue that will probably consume more fluid is going through the process of bleeding the air out of the front lines after putting in the spacers and re-attaching the lines since that will introduce some air into the system. I was similarly in your situation and waited until I had globes and spacers all ready to go so I only had to bleed once.

Yeah that’s what the plan was but they still haven’t shipped and I ordered them tWo weeks ago.
I read that to add spacers, you should drain the pressure out of the front accumulators so you’re not spraying ahc fluid everywhere when you detach… I guess I can work on the other items on the todo list but I really want to get the ahc working

When starting from scratch, meaning if I'm replacing globes, fluid, adding spacers F&R, and will be adjusting sensors, should i first go and set the height adjust offset to zero, to get a baseline then be able to adjust as needed? Or should I leave those?

Had my AHC fluid done at TEQ (Jeboost).

Does this level look right? Truck is on N mode.

Looks good. Just a little over max is fine. The ‘being too low’ is the real problem.

I will leave it be then.

What's the consensus on when to replace the globes...I saw a 10 year / 100K guideline.
I am at 100K now and truck seems smooth on R/T tires.

When you start to feel no difference between the ride modes. If you start adding weight (bumpers, etc.) you will see quickly if they’re worn out. Otherwise let it ride. For reference I replaced mine around 140k-ish but only after adding a bumper and winch

I have bumpers and winch haha.
I am at +600lbs over stock weight. I bet I might feel a diff if I replaced them..
Sport def feels more bumpy. You can feel a lot more road.
I will see how much the fluid level changes from high to low today.
Is there anything in techstream I can look at?

Not sure about techstream, but when my comfort mode started feeling bouncy, that’s when I replaced and it was night and day. With that weight I’d do it

I was at 130k miles when mine indicated they needed replacing.

 

[Bunga]

140k when I changed my fronts. Pretty easy job with the flush 6pt socket.

 

[sticky iqqy iqqy]

at 170k, thankfully mine broke free no problem just with a 6-point 21mm socket.

I purchased four globes from Impex and I’m planning to swap out my globes on my 2019 570 with 120k miles.

Seeing all the people who rounded the bolts trying to remove the old globes has me nervous.

My plan is to get a socket and grind it down to remove the taper. The problem is I don’t have the proper tools to do this. What is the cheapest and easiest way for me to grind the socket down? I tried to find a flat face (no taper) socket, with no luck. I do see extractor sockets, which may also work. But I would like to try the proper way first.

Did mine last week, fully rounded off the head on one of the globes. Hammered on this 13/16 fluted twist socket, used gental force and a long breaker and it came right off.

looking for any insights… I recently replaced the globes on my 2013 with 130k mi. After replacing the globes and bleeding, the ride felt amazing. The ride quality quickly diminished and I figured it was just air working its way out so I bled again, and again, and again. Immediately after each bleed the ride quality became amazing, but only for a day. I see air exiting each time I bleed so I’m not sure if somehow air is entering or there is some other issue. My LX doesn’t sag and all readings in techstream seem normal. Any reply would be appreciated!
