Airbag system leak, but can’t find it

[rommelrommel]

So my airbag system has started leaking lately. It takes maybe 3-5 days parked to get down to the bump stops. However, my bags look very good and I also can’t find any leaks with soapy water. The only spot I can’t really get a good look at is the lines into the top of the bags.

Anyone have any tips or tricks on finding a leak?

You used the soap method, which is a proven way to find leaks. Perhaps check at different heights and see if soap reveals the leak? Honestly, this is a reason people delete the bags.

I very much want the bags, I hate the look of the rear end squatting when you load it up for the woods.

Not trying to mean you need to delete them. Personally, I am like you in thought and my suspension setup doesnt make me have a saggy butt.

Were you able to cycle the bag levels to see if you could see bubbles? Sometime bags wont leak until they are flexed or not in their static position.

My bags looked fine from under the GX, but were actually dry rotted with lots of micro cracks when I removed them for my lift. Sometimes they'd air down at night, other times they'd be fine for days on end. The micro-cracks were from dry rotting and flexing, as mentioned above.

It's pretty hard to access the top of the bags without removing them. If you are going to remove them, you might as well replace them anyway. I really liked my bags, but after doing a coil spring conversion with a good set of shocks, I don't really miss them at all, and don't get any noticeable squat either when loaded up.

Just buying the bags on the odds that the leak is in the 16+ year old bags is starting to sound like the ticket. My bags look incredibly good, but I can only really see the bottom 2/3.
