I also have double convoluted style air springs, not the sleeve style so there really isn't any rolling. In addition, I have the air springs mounted inboard of the frame front and rear, so debris from the wheels isn't a problem like on a land rover. Dust is obviously always and issue.

Thank you for being the first person to give me shit! I can't believe that it has taken this long! In all seriousness I genuinely appreciate the feedback. But I am curious in what you're disagreeing with me on. The fact that a broken pot in my system puts it into manual control mode or that I haven't heard of someone with this system have a pot go bad that wasn't due to improper installation?

I appreciate your insight and experience but the way I see it is that every type of suspension on a car has its pro's and con's. In my scenario, the pro's for air suspension outweighed the con's for it. I am still very aware in how the system works, and know what things to maintain and check-up on.

With regards to water in the system, I have my compressors intake inside of the bus where there shouldn't be any more moisture than what is normally in the air. To combat this I have water traps in-line before the valves, which I empty often. I also do not see freezing temps where I live. Starting the bus with dual carbs without chokes in that temperature is more of an issue at that point.

Then the system just won't be able to level itself automatically. I will have to do so manually (which is how I've been driving it for the past few months without them installed). In the event of a sensor failure, the remote will tell me which corner the problem is on so diagnosis is easy. I've never heard of someone with a sensor failure unless they installed them in such a way that it overextends and breaks.

Um, no. I will add what Iíve seen with servicing Land Rovers that have Air Suspension systems over the past 2 decades. Potentiometer style sensors can Fault in a height sensor application much like Air Flow Meters by getting a worn spot in the resistance section. They also get loose with play and moisture can creep in through the pivot joint with the seal aging.

Keep water out of the system at all costs. Once you hit freezing temperatures it can be stressful to fight erratic valve operation due to water icing up and preventing or restricting air flow. Land Rover has used regenerative type air dryers in their systems to exhaust moisture back out through the dryer in hopes of prolonging itís life, but they still need to be changed from time to time due to saturation.

Air Bladders / Air Springs, UV exposure shortens their life, the more Sun you see, expect dry rotting of the rubber bladders to happen faster. Dust and mud against the rubber as it rolls up or down depending on your height needs of the vehicle act as little knives, cutting into it and also helps shorten the spring life.
Then you can get a leak thatís not visible to the eye, as the air spring folds over that section of the bladder at a given normal ride height and hides it.
It might only reveal itself over a large bump where the spring extends momentarily. We also see these when lifting a vehicle on the service rack and a normal acting system suddenly empties a whole strut/air spring with the suspension hanging down and the air spring no longer compressed like it would be on the ground. The only warning we get beforehand with those failing air Springs is an intermittent high pitched squeak of the air trying to leak out of the bladder over certain bumps while youíre driving.

Not trying to rain on your parade, just giving you 2 decades of real world air suspension issues that are never in the sales brochures... Sad

The heater I got came with everything need to install it including a pump, exhaust with muffler, intake, ducting, controller, and mounting hardware. I'll definitely update when more progress is made on it.

Will you require a fuel pump for your heater since the fuel tank wont be higher than the heater? If so, what kind of fuel pump are you using? a carb fuel pump? ... no... this is diesel. You must be using a high pressure fuel pump with a return line. Well, I'm interested in pictures when you having it all together. I'd like a heater like that in my bus.

Looks like I've been MIA on here for a little bit again. After installing the height sensors, I've just been driving daily, no issues. I haven't been up to much on the bus until recently, except for some maintenance items such as replacing a leaky wheel cylinder and an oil change.

I have on and off been looking for a westy jump seat that was local so I didn't have to pay the big shipping price. They proved to be pretty hard to find, or real expensive. I was thinking that I was just going to end up making one since originality for it isn't a huge deal since the bus was never a camper. A few weeks ago I checked the classifieds out of the blue and found one local for what I think was a really good price. I went and picked it up that day and did a partial restoration on it as it was pretty tired. Luckily, all the wood was salvageable except for the very top piece that has that hole in it. I was able to make a new piece and attach the old laminate to it. The vinyl on the top of the backrest is pretty bad, but it's not a huge deal to me, especially because the yellow of the foam is a very similar mustard yellow.

I had been pretty content with using my coleman cooler as a seat when I needed it, but i wanted the jump seat for a specific reason. I wanted to put a diesel parking heater under it. I had got a heater thinking that I would be able to squeeze it under the bus in a few spots but none of them worked out in my situation. It would definitely work on a bus where you don't have to worry about something hanging 1/2" below your frame. So I've put my heater under the jump seat and it will blow HOT air back down under the floor into the stock heater tubing and go up through to the stock vents up front so I can finally defrost the windshield as well as heat up the whole cabin, and do it quick.

Image may have been reduced in size. Click image to view fullscreen.


The heater runs on diesel so it needs a separate fuel supply. I chose diesel for two reasons. One being that a diesel heater is cheaper than a gas one, and two being that diesel is far less volatile. I got a 4-quart fuel tank for the diesel supply and it will go in the engine compartment on the opposite side of the battery.

The install easy enough so far and looks like it won't get much harder. The only difficult part will be that I have to make a coupler/elbow to mate the heater outlet with the stock heater tube, while snaking between the bottom of the floor and the the clutch and e-brake cable tubes.

Other than that project, I have finally started working on the "doghouse" that will cover the beam. I made template and mocked up a design that worked and have transferred it and cut it out of steel sheet. I still have to bead roll in and work on the access door. It will have a large access door held on with quarter-turn fasteners so I can do things like grease the beam, adjust alignment, check on the bags, etc all without jacking up the bus.

Got the front height sensors installed yesterday after work. Front were a bit more involved than the rear since I had to make and weld on little tabs to the lower control arms for the heim end to connect to. The geometry was also a little tougher to make work since there wasn't much space to work with. Now today I can calibrate the system and the system will have full functionality!

Here's a pic of one of the fronts

So lets say I'm hauling a bunch of stuff but I want to be at my usual ride height. Most systems are pressure based and would keep each setting at a specific air pressure. That type of system would make the bus sit lower than normal consequently. With this system, it is height based so it is able to compensate for the added weight and add more pressure to level the bus out. It also levels in real time so it can adjust to any changes or shifts in weight.


That is awesome!

Started getting the height sensors for the e-level installed this weekend. I got both of the rear sensors installed and got all of the wires ran for the front sensors as well. For the front sensors, I will have to weld on a small piece to each lower control arm so the heim end can mount to it. Heres some pics of the rear ones installed.

If mildly lifted mostly means strengthening things and making it better able to absorb larger movements, then ya, It would be interesting to see what you came up with.

I used to take mine to places I shouldn't have. Now I would not take my bus down some of the roads I did in the 90's. I'm quite sure the crack in the frame, and some of the other broken bits were the result of those roads, but the bus always made it. And faster than my 4Runner would, since I didn't want to stop going uphill! Confused


I agree with you. That type of suspension let's the vehicle stay usable. When I was younger, and involved in car clubs, I always liked the stance of lowered cars, but every time we met up, I would cringe as they scraped across the speed bumps. Crying or Very sad Looks like there are better ways a couple decades later. (starts counting... how many decades? nevermind I don't wanna know) Laughing

Thanks Kevin! After dropping this thing the "common" way and now with air-ride, I don't think I would ever want to daily a static dropped bus again. The practicality with the new setup is great. I do want to build a moderately lifted bay (just lifted spindles and some all terrains)in the future though...

And on another note, I re-made the torsion housing end plates/torsion eliminators to get the heim joints in the middle of there adjustments so I could dial in the alignment better. I now have a perfect toe alignment!

Here's the new piece I fabbed up the other day
