Default Fix a leaking air spring with fix-a-flat?

I wonder if this has been attempted. What is the pressure operating range of the pneumatic system on the AR?

Default Just used the search... looks like well over 200 psi as the minimum

That would most likely be a really bad idea. What will it do to the rest of the system?

Let me know when you try it., then I will estimate the costs of shipping replacement parts to you.

Default as grey-2002-ar-6sp said its not a good idea..

the reasonin is that with a tire the air is put in and it stays in. WIth the air springs the air goe in to rais up but then is vented back through the manifolds to lower the spring. I would think the chemical element in the fix-a-flat could clog up the system: air lines, manifolds, etc.

Default What about something like "Slime" that stayed in the bottom of the spring, where the leak really is?

I would concur that anything mobile enough to travel back through the system would be catastrophic. However, if Slime is used, it would conceivably sit in the bottom, where the leak is.

In fact, I have an airspring going right now, and I have more than enough of slime on my shelves to try this.

I think I could do this with very little danger of system mobility for the slime. And, if it doesn't work out, well, I still have to change the airspring anyway.

Terrible idea to put into my brain.

Thoughts?

This is a bad idea.

Default Compare the expense of replacing the manifold/compressor/lines vs the savings of just ...

... not replacing the leaking bag.

You're more than welcome to try and report on long-term results :-D

Default 200 Psi is the tank pressure not the spring pressure.

Spring pressure should only be in the region of 50 Psi.

Having said that I would not put any of that crud in an expensive system. It will also make the eventual change out a really nasty job.

Cheers

Default Right. What I'm getting at is that with slime....

...which is a viscous, heavy liquid, there should be no mobility above the bottom 2 inches (or less) of the bag, so the worry about travelling to the compressor (!!!) is a worry to the absurd. To get to even the air fitting at the top of the bag, either one of two things must happen:

1. my allroad must be inverted. Not likely.

2. The bag must totally deflate, and since it retains some internal volume/airspace even when the shock is totally bottom out, it must furthermore have all contents evacuated (sucked out). Not likely.

Just saying. I don't think there are valid reasons why this would pose a danger to the air system, but I'd love to hear real ideas on why it might.

Oh yeah, airsprings went up in cost last week, and Carson doesn't have any in stock.
