Drivers side rear bag has a leak. I found it / felt it. Need to replace the bag.

I see this is a frequent question on this site and that anything pre-2000 for Monaco is a crap shoot at best.

I found Firestone Airbag p/n's for front and rear are W01-358-9376 and
W01-358-6905 respectively. These are 9.5" front and 11 or 11.5" rear. I used this link as a jumping off point for my search.

Does anyone know if the ride height for the 92 Dynasty was the same in 97-98?

This is screen shot from pdf I have. I know at one point they measure from different point on rear. Wierd 93 shows 9.5" for both maybe.at bag perches instead of H frame.

Here's a pdf with the ride height info you need

you guys are awesome. Thank you.

I can't see them varying the interface too drastically over the years. If I can find the 10.5" version of the rear part number I listed above, is it a safe bet that will be the appropriate bag?

I just had another thought...The airbag that has the leak is not the bag on the axle. Its a suspension bag, double convoluted style, between the chassis and bottom of the coach.

If there is only one double convoluted style bag available from Firestone for the Monaco Dynasty, that would likely be the one I need right?

Go to the Files section above (top left)and do a search for Firestone. You will find the "Firestone Air Spring Replacement Guide" which you can download and will help you find what you need

I've read the newer larger top air connection is a tiny bit too large to fit through hole in top perch. Owners slightly ground down tips of hex out of bags to fit. I think you need some hex NPT pipe bushings I recommend brass.

Unfortunately that guide doesn't reference anything for the 92 application. It doesn't specify year at all, short of tying it to a Monaco part number, which I can't find for the 92 either.

I got the bag out after I got the levelers working. Don't remember the number, but I'll post it up after I go get a replacement.

I do know that w01-358-6905 is definitely not a rear bag. 99% certain they are front bags on my coach. Gonna hang on to one of those and pick up two rears (one spare).

Here is what I have. I replaced the rear with the 7400 part number. I believe the 6905 is a front bag, haven't confirmed but keeping it just in case. I'll confirm once I solve my next problem!
