Title: MCI airbag replacement
Post by: AndyinCT on February 01, 2020, 08:24:49 AM
Well, I took the bus out to practice shifting, and when I got back i noticed a rear airbag was leaking.  At the bottom where the metal meets the rubber.  It was wet out and I saw the bubbles.

So, is it hard to replace an airbag?  Where do you get them?
Thanks

Easiest place to get them is from Luke at US Coach 856-794-3104

Also Mohawk Industries if you have the part numbers. You can get them just the bags or fully loaded with the new rings on them and the new bolts unless you can save the ones on your coach. also here

With the bag inflated, even though it is leaking, remove rear wheels on that side. Install a spacer from a piece of 4x4 between bump stop and axle housing. Let air bag bleed out or unhook leveling valve on that side. Remove all attaching bolts on top and bottom to remove bag. I would use all new bolts and nuts, washers. If it is a double old style bag, that is why new hardware. Those specially made heads can spin easily when tightening if threads are bothered. The new style bags are held with only a couple of large bolts. Luke is a good source. Get the right parts the first time.

   HI;
     Just curious;  like to know which "rear" air bag? I replaced the air bags
     on the drive axel. Not to bad a job.  But the bags on the tag axel was
     another story.  I had to take it to a truck garage that used a torch on
     the bags.   (no access) 
                                      Good luck,   Merle.

Hi Merle,
Its a drive axle bag.  On the right.  I may have a garage do it mainly because I haven't had much luck getting lug nuts off this thing!

I would cost out doing all 4 at the same time as when 1 goes the rest might not be far behind to do the same
