First noticed the passenger sir bag deflating when sitting more quickly than the others, the on some rough secondary roads had to stop, put in neutral and allow the front to pump up, now both air bags are not fully filling and will loose air more quickly than the rest when sitting.

2003 air bags probably cracked and leaking.

Going to soap them up tomorrow and see. Also thought height adjustment valve might be shot.

Could be valve also my bet is bags. I would check rear bags while you are under there. A blown bag is worst than a blown tire.

I replaced the bags on my 02 last year. They were it pretty rough shape. Glad I changed all 4.

Did you do them yourself?

Jthigh · 11-24-2022, 08:24 AM

Yes, I installed myself. I was able the replace them without removing any of the tires. The rears are pretty easy. The fronts are a little more challenging due to the upper A Arm brackets. No special tools needed, just a good wrenches and sockets and torque wrench. I used the leveling jacks to raise coach and then put 20 ton jack stands under unit. Had to purchase some new hardware because some threads were messed up due to rust and front new bag bases went from SAE to Metric.

Hi jthigh Great Job I have a 2003 same Chassie. I would like to have the Part #s and brand that you used. Thanks Jim

If you call Spartan and give them the coach ser.# they can and will give you the part numbers and even sell them to you right then over the phone.

Here is a link to the thread I did when I installed my air springs. All the info is in it. I did mine a while back when there was a supply chain issue with getting the original Firestone bags for the rear. Had go with alternate manufacturer for rear bags. Been out a couple times in the Smokies and West Virginia mountains and seem to do fine.

I never tried to post a link to another thread before so hopefully it works.

Wasn’t sure if that thread listed the front bags. It mainly focused on the rears since I was having trouble finding Firestone OEM parts.

Here is the front bag OEM parts I installed.
Firestone Airide Air Spring | Reversible Sleeve | 1T19G-8
SKU: W01-358-9825

Those are for the Reyco Granning IFS1370. You should verify your chassis components.
