Steve,
Support the coach under the rear support points with the coach fully raised. You want the air bags on the coach fully extended so you have the maximum room for the replacement bags.
Exhaust the air from the air bags using the level low when the coach is supported.
Life is really easy if you can take the tag and outer drive wheels off.
With that access it is easy to remove the fittings (replace with compression) and the 2 3/4″ nuts from the bottom of the existing air bags. With no air in them push them down a little and tip them out of position. I think the front drive axle shock needs to come off.
The drive axle air bags come out on the side of the coach, but if I remember it is easier to replace the tag axle air bag from beneath the coach.

Thats what I needed to know. Already did front ones. Thanks Jon.

But Dan, you didn`t get the satisfaction of dirty hands and busted knuckles !

Thanks Tom. Exactly what I was looking for !!

Steve, actually did on the front bags after alot of cussing and contemplating over a cocktail, I figured out the left side wheels are left hand threads! If you happen to run into the Robeson’s, Joanne tells the story best.

Yep. Righty Tighty Lefty Lucie all in opposite. Seen this happen before, hilarios when all said and done.

That coach is not properly supported. I especially am concerned about the presumption a hydraulic jack will not fail. They will and it will come down until it reaches the bottom of the hydraulic travel. Maybe I am a chicken but after using hydraulic jacks to get things positioned I then use a stand or blocks of hardwood.
I am hoping the orange stand is of sufficient capacity under the support point. It is likely to be carrying about 8 to 9 tons on each side.

Jon, you’re missing the silver stand, visible under the drive hub. Looks like it is supporting the real weight

Sheesh, it was a work in progress and I guess I should have used a wide angle lens for all the support points. The jacks were used to make air bag and shock holes to line up. There’s nothing unsafe about it.

Now I see the silver stand. I usually support under the square tube behind the tag, but the front is also acceptable.
