My AHC failed (1 Viewer)

[g1701gst]

I had a similar issue, leak from near the driver's side rear. Lost fluid and the vehicle was stuck in low. It happened while I was driving slowly offroad so I noticed right away when the fluid hit the exhaust and was smoking. I pulled the AHC fuse to save the pump and drove it the 100 miles back home in low rider mode . Initially, I thought the leak was coming from the top of the shock but eventually found it to be two lines that crossed too close and wore a hole in one. I bent the bracket that held the lines further apart, replaced the two lines and bleed the system again with new fluid. Been good as new for the last year.

Here is the parts schematics, highlighted lines below. Where they cross circled in red is where I found the pin-sized hole.

Here are all the parts and part numbers I used, removing the muffler provided lots of room under the vehicle and I replaced all the gaskets which I think are single use:

Part Number	Part Name	Price	Quantity	Total
49164-60023	Hose Suspension Con	260.87	1	260.87
48997-60010	Tube Height Control	66.85	1	66.85
48942-60020	Gasket Height Control	2.64	1	2.64
44327-30040	GASKET, PRESSURE PORT	2.64	1	2.71
08886-81221	Suspension Fluid	13.81	7	96.67
Muffler parts:
17451-0D140	Converter & Pipe Gasket	30.72	1	30.72
90917-A6003	Intermediate Pipe Gasket	12.26	1	12.26
90917-06093	Tailpipe Gasket	14.36	1	14.36

The rubbing location was about 5 inches from where the line attaches to the top of the shock.

This is the bracket I needed to bend, I now have about a 1 inch gap between the two lines.

Here are a few more pictures

^Good stuff!!

This probably deserves its own PSA announcement for everyone to check. Bad on manufacturing for not catching this in production!

I'll go check mine as well.

Wow thats great info g1701gst! Thanks for the post. I dont think i will attempt this repair on my own but great to know for others who might read this thread.

How is the estimate from the dealership for the repair.

Funny I have the same issue today in Pittsburgh...what are they quoting you to replace the rear shock and hydraulic line? I'm waiting for my quote

Supposed to get my quote tomorrow.

With the AHC in high and using a flash light, you can take a quick peak from the wheel well. I was able to see where the black paint wore off and it was shiny but it is hard to see how close the two lines are without looking from below.

Do you need to remove the spare to see from underneath?

 

[2008LX]

Here's the estimate I received. $1,911 total. Seems very high to me. Idk what their labor rate is.

Did they indicate whether it was rust or those lines wearing through?

I havent had a chance to call him yet. I'll be able to talk to him later this afternoon.

Need no, but with it removed you can get a real thorough look at everything up there.

He said it was rust. They are reworking the quote based on the fact they just inspected and flushed the system about 8 months ago and didn't give me any notice that the system had issues.

That sure looks to me like failure due to two metal parts rubbing together, not corrosion.

Are there any concerns with replacing the battery myself? With these modern cars I never know if there are complications when putting in a new battery.

 

[CharlieS]

No, it is a one banana job. You can do it in the parking lot if you have the two wrenches you need - 10mm and 12mm (fixed thanks @bloc ).

No, it is a one banana job. You can do it in the parking lot if you have the two wrenches you need - 10mm and 14mm, I think.

Thanks thats good to know. I told the SA I would do it myself and he was like "Really? Its $99.95 installed with a 7 year warranty!"

So I'm going to let them do it. I don't think i can do it any cheaper than that.

That's a good price IMHO.

That's a good price IMHO.

Theyre having a sale so its normally $150 installed but even that is a good price. You can't get a battery much cheaper than that even if you were going to put it in yourself.
