Air Bag Air suspension problem + need help

This newbie needs help. Today I was leveling our 2005 Monaco Safari Cheetah 40DST before installing the new Levelmate Pro. In the process of getting the rig level I raised the wheels off the ground briefly and that was followed a pop and hissing sound. Exploration led to the realization that my driver's side air bag had ruptured.

Now, this might have just been bad timing and the bag ruptured because of age. They appear to be original so that would make them 14 years old. So this has lead to the following questions?
1) is it safe to change the one bag or should I take this opportunity to change them all?
2) How do I identify the model # of the bag and where should I look for replacements?
3) I am fairly adept at mechanical work but also 65. Is this a job I should able to tackle or is it best left to a professional?
4) When changing the air bag (s) is there anything else I should do or look for at the time?

I look forward to reading your advice.

They are not that hard to change but a bit dirty down there

I would never change just one, always in pairs and given the age of yours, all of them

I am over 70 and I have changed them recently but not on my motor home

They are likely Firestone and they are all stamped which should be visible and the original data for your MH will denote the brand and type installed then

The lines running to the air bags should be inspected closely and if any abnormal wear or checking then change them as well

looking forward to other replies

Air Bags

Thanks Milford. Your reply is encouraging. I looked but did not see any markings or labels on the bags. Attached are several photos. I looked in the Owners manual and on the Vehicle Data Card but I can not find reference to the air bags. Hopefully someone will know the details or where I can find it.

Limiting straps can possibly prevent that from happening again.

Give Source Engineering a call. They are old Monaco employees that started their own business. One of the products they sell are airbag kits for a better ride. I'm guessing they can name the bag numbers off the top of their heads.

No guarantee they will be legible, but I found part number labels on the top plate of the Firestone air springs in my coach. If you find the number on the bag it will be for just the bag, not the assembly, in my experience.

Go to Files above and do a search on Firestone. You will find the Firestone Air Spring Replacement Guide which should help you identify your air bags.

Air Bags

I contacted Firestone as that was the only air bags (suspension)reference in the owner's manual. They gave me two possible part number W01 358 9376 and W01 358 9651. In searching for these on the web I found that these air bags from Firestone are available, but also from Goodyear, Black Tech, Spring-Air and others. The prices can vary from the low $100s to over $200. While quality is very important I am not married to any one brand for brand recognition alone. Most are only warrantied for 2 years so that is not an issue and from what I have read from the various posts the air bags should be checked regularly and changed when they show ware, damage or aging. While Firestone is the larges supplier of suspension air bags (they claim on their site) have any of you had experience with the other brands?

Air bags

Try this - Contitech AS 8897 at Find it Parts $121 free shipping. This bag has 3/4 pipe tap for fitting. Can be used on rear with 1/4 pipe tap, use reducer bushing. Firestone 8897 is the same bag. Firestone 9376 is same except has 1/4 pipe tap. Google search in Monaco owners forum; 2007 Monaco Dynasty Air Bags. Much info about part numbers and tools needed to do this job.

The maximum length of shocks should limit travel before air springs are extended to breaking point, for either solid or independent front suspension; although solid front axles are discouraged from lifting wheels of the ground due to weight placed on shocks.

Air Bag w01358-9651 for front of 2005 Safari Cheetah R4R

Thank you all for replying. I have finally ID'ed the bags as Firestone W01-358-9651. The problem is now it appears this item has been discontinued. Do any of you have a coach on an R4R Roadmaster chassis that uses these bags and if so have you found a replacement? If so, please let me know the details.

Some time ago this problem arose, the member published the replacement air spring # from a different mfgr. Use the google search box at page top to search irv2.com

NOLAfolks, I have an 07 Neptune and probably have the same airbags as you. I replaced mine several years ago with the bags that come with the ride enhancement kit (REK) from Source Engineering. IMO, the extra money for the complete kit versus just factory style airbags is well worth the money. It really helps with softening up the ride. I looked at my old airbags I removed from my coach a couple years ago for someone else on here and was unable to find any numbers on them best I recall.

I would think you could find an equivalent replacement for them by cross referencing to another brand if you choose to go that route. I'd be glad for you to have the bags I removed from my coach just pay shipping. However, they were on my coach for about 6 years and been stored in my shop for nearly 6 more so they are still old just haven't been in service. HTH

Chad
