I have a 2013 LX570. One of the hydraulic lines on the AHC system burst with just 86,500 miles on the odometer. The dealer says this was due to rust and corrosion. To replace the line I was told that the body must come off the frame. Additionally they can not say if other parts need to be replaced due to the corrosion. Because they can not pin down a price for the repair, they quoted me a maximum $36,545. This is the cost to replace the entire AHC system, if necessary. I believe the entire vehicle only has a value of about $40,000. Do I OK the repair and hope the bill is nowhere near that high, or do I write off the truck? Is there an aftermarket conventional suspension system that can be installed? Other than the suspension issues the truck is in excellent shape. Thank you in advance for any advice.
 
Yes, suspension can be swapped to a conventional land cruiser suspension (or Tundra front, LC rear) if it comes to that, but would be missing the KDSS sway bars that make the LC handle as well as it does on the road (can be compensated for with aftermarket swaybars). But research here on MUD for AHC issues and repairs before committing to any path.

Step #1: walk away from the dealership and never look back.

The question is……if OP is not handy to do the fix on his own…….and dealer is asking for that $$$$……what are his options? Most 3rd party repair shops won’t come close to AHC even if their lives depend on it…since 99% of them have no clue what AHC is. And those that are willing to take a look are probably going to make it worst.
 
If unable to find a shop or do it on your own, next best option is to sell the LX. Ideally on MUD or to a local LC club member.
 
I can't even imagine the look on a Service Advisors face when he's quoting a repair bill of $36k to replace a hydraulic line.

To help ease the shock. Here is a picture of all the hydraulic lines. I think it’s usually the one I marked in blue that leaks. Possibly the red one. A few people here have had to replace it and will know better. I’m sure whichever is the common one, the truck doesn’t need to be removed from the frame to replace.
Just hoping to demystify it a bit. Nothing a good brake repair shop probably couldn’t repair, plus I’m pretty sure all the replacement tubes are still available from Lexus/Toyota. All of the parts in the system that aren’t hydraulic lines are readily replaceable as well in case it’s leaking from something else.
 
Pics of underside?
 
dirty service advisor = early xmas present!
 
Seems unconscionable that they'd not try a more responsible and economical repair. That quote is ridiculous. Sounds like they're playing games. Are they also trying to sell you a new vehicle and are "willing to take this on trade, despite the issues"?
 
I forgot to add, as others have said, walk away from that dealer. They aren't treating you fairly.

If you can locate an independent Toyota shop or even 4x4 shop, they might be willing to think more creatively. The challenge is finding someone who is knowledgable enough about AHC to be sensible about repairing or replacing. I'd skip right past any dealer and go to the independent small shops.

If it is more work than you want to tackle or deal with, find an enthusiast to buy it - I bet there are a bunch of people here that might consider this as a project. I'd speculate that the 'mud LX470/LX570 crowd has as much or more AHC knowledge than any US shop you're going to find (except maybe outside of a few big name cruiser specialty shops). People here can probably help a skilled DIYer through the repairs.
 
I think I’d be on the phone to toyota corporate asking for the regional service advisor. The tech for the techs…
 
if all else fails, i would be happy to take it off your hands and pick up all the headaches whatever comes with the deal :)

Thank you for the advice. I'm still waiting to hear back from the dealer after our initial conversation. I am inclined to walk away, but finding someone who can address the issue in my area will be difficult. I am going to make some calls.

Agreed, I am looking for options. The area I live in is not known for off-roading, and finding a specialist will be difficult. I live near Albany, NY. If anyone can recommend a specialist in my area that would be great.
