Hi all,
Just a quick update. Got the air springs installed  on the left rear yesterday. Everything worked great. The coach aired right up. i crawled back under and leaked checked the bags. No bubbles showed anywhere no air noise picked up with my leak detector. Every thing good until this morning. Left side lost some air overnight. Not all the way down like when the bag blew, but still noticeable. I have an idea what it might but I would have expected to find the leak when I checked yesterday.
I had trouble with the 45 degree elbows that connect the bag to the 1" airline. If I tightened the fitting all the way on the airbag, it would not line up with the air line. I had to back it out nearly 3/4 turn to get alignment. I was surprised that I didn't find a leak yesterday.
If anyone as any tips or tricks on how get a tight fit and alignment at the same time, I'd appreciate your input.

Tony, Did you use a thread sealant on those threads. BTW if you end up needing a replacement fitting I have some that I removed from my coach.

Tony, as Hossier mentioned thread sealant will definitely help. I like to use Rectorseal True Blue, it works fantastic. As with any sealant it’s important to check to make sure that you’re not getting it inside the fitting, with 1” fittings that’s not that hard to keep clean, much harder when your dealing with 1/4” or smaller fittings.
The other thing that I will mention is something an old plumber told me on the job, do not back off the fitting, if you do then you need to start over, remove the fitting and reapply the sealant. Then creep up on the spot where it needs to be aligned so you do not have to back the fitting off.

The other thought is maybe it’s not leaking anywhere you touched, maybe it’s the six pack leaking or the leveling valve? There are two exhaust ports on the back of the six pack that you can listen for leaks or spray them to check for leaks.

Thanks all for the pointers. I used Rector seal 5 but probably did myself in when I backed off to line up with the airline. I will pull them tomorrow, clean them up and starT over. I have some Tru-Blu and will give it a shot on the next go round.
@Hoosier, appreciate the offer for the fittings, but Richard already sent some.

FYI, I also have some of those fittings as well as the old lines. I deleted mine and went with 1/4” lines so I no longer have a need for them if someone else needs them.

Loctite 545. And like others said, don’t loosen once tightened.

Never had a thread leak with the Loctite 545. And I don’t have to gorilla the fittings either.

Thanks for the update.

What bag number did you end up using??

Its been a while since I posted on this topic. I was looking forward to sharing my airbag adventure and telling the rest of my story. I still plan to do that, but first I have one last (hopefully minor) issue to resolve. Last night I finished installing the last air bag. Since I used some Loctite 545 on the airline fitting going into the airbag, I needed to let it set 24 hours to cure, before airing up. So far so good. Then today, not so good.
I started the coach and let the air pressure build to 125. No problem. I was already in level mode, started the process of raising the coach. Keep in mind, my HWH system was cobbled together by Newell, with components from HWH. This was before they actually started getting systems from HWH. I can raise each corner of the coach individually, or all 4 corners at the same time, using the master switch. I do not have automatic leveling.
Anyway, back to my issue. I already had air in all bags except the left front because that was last set of bags I replaced. When I toggled the switch to raise the left front, nothing happened (except the horn started honking). That interrupted me for a minute while i pulled the horn fuse and reinstalled it (no more honking). Normally, when I am raising the coach, the air pressure bleeds off pretty quick. In this case, my gauge didn't budge, and the coach didn't move. I played around with it and couldn't get it to do anything. I tried to lower the coach at each corner, and that didn't work either. I have power to my leveling control panel, and it was still making the annoying alarm sound like it always does when it's in level mode. I checked the fuse for the Leveling system, and it was fine, but I replaced it anyway. This is where I'm stuck. Any suggestions or ideas on what check would be greatly appreciated. Once this is resolved, I will post about my airbag install and all the fun I had along the way It really has been a great learning experience.

Tony and I just spoke, let me summarize for those following.

So first order of business is to determine if this is an electrical or pneumatic problem.

Step one, lay under the front left and stare. After all, lots of contortions, wrenching, and coach yoga where all the wires and air lines are located when you are working on the front left.

Step two, put coach in level mode, and see if raise solenoid magnetizes. If it doesn’t then pursue electrical troubleshooting. The horn beeping may be clue, or it may be a distraction.

Step three, assuming the raise solenoid activated in step two. Disconnect the air line from the six pack to the ping tank. Cobble a fitting on the air line to provide air pressure from an external source to the ping tank. The bags should inflate. If not look for a loose or pinched air line.

Step four, if the external source inflates the bags, then activate the raise switch, air should come from the back of the six pack.

There are a couple of gotcha’s. One, the coach is up on jack stands, the height control valve will think the coach is high and will not inflate the air bags in travel mode. Two, best to provide air pressure with an external compressor vs with a running engine, just because you can’t hear anything with the engine running.

And it’s not clear to me, if the entire system is not functioning properly after the horn beeping, or just the left corner. If the entire system is inop after the horn beeping, then it’s an electrical issue.

Good hunting!
