345 LE. Air ride bags leaking
Hello I'm a proud owner of a 90 345. I think it's a 90 the plate on dash reads 12/89 so I think it's a 90 it looks differnt then the pics of 89s I've see on this forum. We are trying to get a early start to our season to get our projects done so we can go to a seasonal spot for the summer. We fired it up today and moved it to our drive way and I noticed the pump under bed never stopped running and of course the rear driver side bag has a hole it it. So I'm looking for advice and guidance to get this fixed. It just goes on our list of the other projects we are tackling. We removed rear queen and putting in 2 single beds. Any input would be great. Thanks Richard

I'm trying to make sure I buy the proper bags. Here is a pic I was able to get today of bag and plate on the crossmember. Does anyone know what this bag part number would be. From what I read part number is under the Firestone logo.

No that gap is not common. The bolts and rubber bushing need to be replaced. With the bolts loose like that I feel they could eventual break or snap which I don't think would be a good thing!

The Rear Air bags on the 345/350 are a royal pain. I know there will be some differences from model to model, but let me share my experience:
Unless you want to cut access holes in the floor above, you will find that the upper 2 bolts are extremely hard to reach.
But, to make it worse and please listen closely, if you have a T air fitting on top of one of the bags, you need to tackle the situation very carefully.
Here is one solution that worked for me you may want to consider.
After you painstakingly removed the upper two bolts in that very tight spot (and you already took out the lower bolt, drop the bag down enough to get a wrench on the T-fitting and rotate the bag to unscrew the fitting.
This picture shows the T-fitting after the bag was removed. Some teflon tape on the thread and rotate the new bag onto the T-fitting.
If you try to unscrew the airlines in that tight space above, you may find yourself in a real big mess, besides the problem with dirt and cross threaded fittings.
I hope this helps and saves you from a nightmare scenario.

Thanks for the input I think I will be doing a access panel. I also asked ACS to supply any and all part pints etc. I will share when I receive. He didn't give me a part number on the phone I just read him my plate and he told me a bag price. $180 per bag plus shipping, but now I have confidence in I'm receiving the proper bags and a help line if needed.

Honestly, I don't think $180 per bag is that out of line. Of course, I haven't priced them, so......

Bags are finally installed and working. What a pain to remove the top bolts.
Now I'm going to fix my sway bar while I'm under there I'm going to check my rear diff fluid. Any input on what gear lube to use. Thanks

How did you deal with the air fittings, did you have individual fittings or T's?

I had t fittings I replaced them with the Parker air brake t swivel push fittings and air brake hose from McMaster Carr $50 for hose and fittings. I coiled up extra hose and spliced into original hose so I can replace the rest of hose and fittings at a later date without having to open up the floor again.

Congrats on getting the new bags installed, and thank you for the part number. We need to do the same on our 88 real soon now.
Rear Sway Bar - ours was out of the bracket when we bought our motorhome. The dealer we bought from fixed this and a few other things, and after 11 years of light use it is still in place.
Rear Diff should take the standard 80W90 diff lube that most open differentials use. You can go synthetic, but fresh clean fluid will be a significant improvement.
