Foul Sir, I went off roading on a squirrel in my 15 LX at 50MPH today. I doubt a non AHC vehicle could handle that level of abuse without aftermarket lift and suspension.
LOL! Just because a rig is capable of such, does not mean the owners are aware/put the capabilities to use. It's true though, i went LX because i can't afford to buy a car then heavily mod it b4 its off-road ready, and with LX you just slap on 33-35in off-road tires and you're set. It's also true though, that LX owners are more mall crawlers and soccer dads, which is a very good thing for enthusiasts who are looking to buy but can't afford new: LXs are generally well-taken care of and less abused than Land Cruisers (less off roaders in new LXs vs new LCs).

I too, love flying down dirt roads with the AHC system set to comfort! It's amazing how smooth the ride is from the inside even though im flying over bumps.

Oh yeah. I think people in some cases look at the AHC as sort of delicate. LX is fully capable to jump dunes, curbs, pretty much anything within reason.

People jump sand dunes in the Middle East in these things like people do with Raptors. AHC is ready to be abused, just change the fluid every 75k. People forget just how much R&D goes into EVERY facet of these things.

This person in the video I guess wrecks but he clearly was drunk or something definite jack ass, I'm just showing what these can do.

 
When under the truck - what/where is line connected to and located? Trying my best to visualize the system and find the suspect line without the video. Appreciate the help!
I believe that part is on the frame above the muffler.

The line is just above the rear axle running right in front of the crossmember. The lines connects to the line that might rub right at the rear driver side shock/ spring. In the two pictures, the red arrow is the line that might rub and the green arrows are the line that rusts. The second pic is looking at the crossmember from the front to the rear, right above the rear axle

Want to resurrect this topic :) I have the same line problem. Can someone share that part number?
Thanks!
@NYC570 - it looks like you are the most experienced on this topic :)
 
Thank you for reply! I've ordered it through one of the local dealerships and will receive it in a day or two...
Stopping by to revise this topic due to my dreaded rear line going out on me. Shout out to @NYC570 for swooping in for the win with the part number.

@ofreema, if you don't mind me asking did you ever complete this job, or did you have the dealership due the job for you? Any info/knowledge that you can share with us Lux Cruiser owners would be greatly appreciated 🤙🤙🤙

Bumping this up, I am seeing 3 part numbers mentioned previous (48997-60010, 48998-60010, and 48999-60010) but the line that is so prone to bursting above the muffler is 48998 correct? My lx just went through the lovely driver side puddle today

That's the Middle East. He was unlikely to be drunk.
 
Here's a short video of the tube that failed because of rust on my 13 LX. At this point it's partially removed. The picture shows the new tube compared to the old one. If you don't want to replace any brackets, you only need to unscrew the tube at three places. I decided to replace the two brackets that hold the tube as well. They're fairly cheap.

The part circled in green is easily accessible and wasn't that much of a problem. The part circled in yellow gave me the most trouble. It's very tight in there. A mixture of fixed wrenches with different angles as well as a set of ratcheting wrenches helped a lot. The part circled in red is where my tube failed because of the heat wrap. I painted over the heat wrap on the new tube with high heat temp paint to prevent this from happening again (blue arrow). I'll monitor the tube yearly to see how the paint holds up.

Overall this isn't that bad of a job if you have a decent set of wrenches and don't round one of the bolts like I did. I also had to unhang the exhaust from the three rear rubber hangers to allow the old tube to come out and the new one to go in.

I have the same fluid leak as you (48998-60010 is leaking at the heat shielded spot) and need help! How did you get to the section circled in Yellow? I'm having the hardest time with these lines because they're corroded together and in tight spaces.
I ended up dropping the exhaust to get to the section circled in green and I still had a hard time getting it apart. At the sectiom circled in yellow, I got the bracket removed but i can't get lines apart. I was actually going to take out the connected section (to the fluid tank- 48999-60010) but can't even get that line off of the tank. I have been using WD penetrant spray but nothing has worked. Even if I can get the lines apart at the yellow circled area, I don't know how I will reconnect them in that tight space? I could barely get the bracket off at the yellow area circled. Any help would be great! Next step is a mechanic and don't want to spend $1k for one connection point thats corroded.

To me this was the hardest part. I believe I loosened the line first before umbolting the bracket. I used two small wrenches to hold the line and loosened with the other. Make sure you're actually loosening it. I remember that when I was putting it back together, the two lines weren't tightening up. Because of the position they are in, I got confused and I was actually loosening the lines again. It's very tight in there, but it's doable with a bit of patience.
 
The line that pops is on the driver side above the exhaust. What causes it to corrode is the heat wrap retains moisture, and slowly eats away at the line itself. Here's a pic of a line that I've changed with the heat wrap peeled away :

Edit : When I do change them out, I remove the heat shrink on the new line and coat the lines with either fluid film or cosmoline, and apply copper anti-sieze to the new line's threaded fittings.

Here’s what mine looks like. Something sprayed AHC fluid all over the drivers side rear, smoking like a demon. Think it’s the culprit?

The side above is pretty dry. Here’s the wet side (towards the wheel.)

The union nut (?)

The entire frame is soaked up to the Center Unit.

Opinions welcome.
 
On the driver side ahead of the rear wheel there is also a big valve block. There are also two lines that run from the pump across the frame to the driver side. They are tucked above the exhaust and fuel tank. If you saw smoke I’d check those. The one the unions above the exhaust goes to a driver side valve. I hope it’s not that one because it’s a nightmare to get out.
