My rear air bag on the driver side is leaking it's the one between the driver's and the tag any info for a repair would be very cool. The rig has 80,000 miles

Are you sure it's the airbag and not within the air system, possibly a line or loose fitting.

I agree with Jim. Most of the air leaks are in the air solenoids, or the air fittings where the air tubing inserts.
The air bags are double layered and usually the last part to leak.

However, if you need to replace an airbag here are some helpful links:

Yes I'm sure it's the bag. I can put my hand on the leak, and feel the air coming out. and watch the coach drop slowly

Well I called Monaco for a part number and a price WOW the price was $658.00 each Part number 10108394. Then I called Veurink, Rv they came back with a bag by Contitach. with first price $388.00 then a lower price of $300'00. Is anyone familiar with these. Or has anyone used them on there coach. Also. looking for my last two air bags on the tag, but I can't see them from the wheel well. I'm also trying to locate these air bags in California to save on shipping. Thanks again to all of you guy's

Quote from another thread:
Contitech AS8897 - Find it Parts $127 free shipping. I used these on my coach (05 Signature), should work on yours. This bag has 3/4 NPT for air fitting. You might need 1/4 x 3/4 bushing; I did on some of mine. Hope this helps, Mike.

Here is a link to MJ's website showing the Contitech AS9376 which is the direct replacement for the Firestone W01-358-9376 use on many Monaco coaches from the early to mid-2000's.

The worst one on my 2003 Dynasty was the one on the rear of the rear H-frame. It was positioned between the drive and tag axles when looking at it.

I feel these ones are the most exposed being directly between the drive and tag tires. Mine had a pretty nasty chunk taken out of it but wasn't leaking yet.

I have attached a picture of mine.

I replaced all ten of my air bags about a year ago and it was well worth the time and money to travel with peace of mind knowing they are all in proper condition. Mine were weather cracking pretty bad, another pictures attached of what they were looking like when I removed them.

The best looking ones were the two for the tag axle which are mounted inboard of the frame rails and therefore protected from the elements a bit better.

I have a full write-up on my coach thread showing how I replaced mine. I used Contitech AS8897 air springs as that is what we use at work with great results.

I’d replace them all- they’re old enough. You don’t want to be caught in the middle of nowhere needing an airbag. I had a leak in one and replaced it. I looked closely at the others and decided to replace them all. I did 7 in one long day.

There's a link to the thread on our 2003 Monaco Dynasty in my signature. If memory serves my FASS installation and air spring replacement start around page 88 or so.

rory .miller · 04-27-2022, 10:08 AM

thanks again I will look it up

jdw1 · 04-27-2022, 09:31 PM

What’s the part number for the two bags on the tag axle?

Thanks

Not sure who you are directing the question to but on my 2003 Dynasty all ten air bags were the same. OEM's were Firestone W01-358-8897 which crossed over to a Continental (Contitech) AS8897.

For a while Monaco used different air springs front to rear based on air inlet port size but eventually just went with all of them using 3/4" NPT and reducers.
