I made a socket to remove the elbow like Scott did as I don't have a crows
foot.
I have crows feet wrenches in three different styles. The white tool fits over the top of the fitting and can be used with a 3/4 gearwrench or my modified 3/4 gearwrench on the front to air bags. After about 3/4 turn the fittings should be loose.

The best part of my set is the locking impact extensions which lock onto the adapter wrenches and you can hang the entire setup on the nut without it falling apart.
I'd do these everyday if someone was willing to pay 50$ a bag installation. I may have a third set to install but I think after that there's no more in Boulder City that need changing

Shocks are on my list for early next year. That's pretty cool that you guys make your own tools... My airbags were replaced a few years before I bought my coach but if I ever have to replace them again I'm coming to you... For helping figuring it all out.

I am buying contitech as9449 air bags and Gabriel shocks.

I plan to change by myself.

However, I search on the forum about how to protect the air spring, I get a lot of posts. But I can't find a picture to demonstrate how it should be done.  Here is my plan, please let me know if there is any issue.

I plan to use 6x6 treated wood, cut to 8.5 height. that is the ride height. I know forum recommends 2" receiver hitch.  But I don't know any welding shop near by that can do that. I can just go to homedepot buy one 6 x 6 x 8 foot.  Somebody mentioned the treated wood can support 7000lbs.  If I use 4 to support the body, it should be enough.

I plan to change front axle first since it is leaking the most.
Air up the bag to ride height, then put multiple (4) woods on front axle to support the body.
Use 20 ton jack to lift the one side tire off ground.
Use two 6 ton jack stand to add extra support.
Use the torque multiplier to loose the lug nuts.
Take off the tire.

This should give good clearance to access the air spring.
Replace the air spring, replace shock.
put back tire, torque to 450ftlbs
Repeat on the other side.

No you raise the coach and install the safety bars. Takes a little practice to get them in the front sometimes using the left or right raise arrows. Also helps if the governor is set for 130 psi.

Running,

You will find that you need to loosen the lug nuts prior to lifting the tire off the ground if you are doing them by hand. What year coach are you doing this on?  This will help determine if you have Budd style wheels or hub centered wheels.  If Budd wheels left hand threads on drivers side. 12" safety stands (blocks) will give you lots more room if you are a little fluffy around the center section.

Treated wood is usually Hemlock, not the strongest wood. When I did my airbags I used 12 inch blocks and since then I have made
12 1/2 inch blocks. The blocks that came with the coach, some were fir and some were hardwood and they were 2 inches by 4 inches,
actual size and my new ones are 4 x 4 inches all hardwood.

The coach is 1991 grand villa u300

It doesn't have the hwh leveling system in the later model.

I am not sure if it can raise all the way to 12 1/2 inch.

If no need to cut, I might just buy the receiver hitch.
Do I need four of them?

Do you have hydraulic levelers?

You stated in reply #24 that you were buying Coni Air Springs. Then in Reply #30 state that "It doesn't have the hwh leveling system in the later model." I'm a bit confused on what IS being worked on. Can you add more detail info?

1991 GV doesn't not have auto leveling system. It has 8 air bags. It relies on a manual leveling system by pulling three levers to control the height of the air bag.

Then raise the coach all the way up and block the trailing arms to the frame. Maybe someone with your year coach can post a picture.

It should still be able to raise enough to get the safety stands in. Just pull the levers all the way back with the coach running until it won't raise any further.

exactly how I did it...my safety stands are 12 1/4" and in some positions still have 3/8" clearance when in full up position...good time to replace your air tank vent valves too..
