Default M380 Ride Height Adjustment (also other Wanderlodge models)

We got off topic on another thread and a couple people asked to start a new thread about this. It appears that several people with M380's have had ride height issues and some of us have lost tires over it so I thought it might be important to try and show what is causing the problem.

In my opinion there is a poor design on the end of the height control valve arm where it attach├ęs to the steel rod coming from the suspension. I have no idea if all the older Birds are the same or not. My problem was the allen head set screw (see picture) came loose and the control arm was free to move at will up and down the rod changing my ride height as I drove. Not knowing how it worked or what problem was I finally discovered this, adjusted ride height, and tightened screw real tight. 4 months later the front and the back left did the same thing again. I tried lock tight on the threads, same thing. So I fixed problem with a couple cable clamps as you can see in the picture and no more problem.

Although this fixes set screw coming loose there is still a issue of the little swivel breaking which has happed to one other owner I believe. I think this is a real flimsy way to do this when this arm takes such a pounding going down the road and when it breaks your ride is all over the place.

I hope pictures make it, my 1st time to send pictures.

Lloyd,

From what I can tell, that's the same setup used on my bus and used on every Wanderlodge that I've ever seen. There must be something different that causes yours to fail. I have 100K on mine with no problems. Hmmm

Looks familiar, I think it is the same on our 88. Never has been a problem.

Maybe the newer ones are made in China.

You might want to spray the swivel joints with some white litheum grease, if not lubercated these will sieze up and snap off. This happened to me on my first day of ownership of my 88. It gave me the impression that I had a blown airbag because my left rear was sagging. This is a small part which is not readily available and it could leave you stranded for a few days, I was able to find a suitable sub at NAPA. I now carry a couple spares.

John,

Thanks for the tip. I have already sprayed grease on mine too. Guess I should have replaced the little suckers if I could find one like you did. I think my front one must have been defective because no matter how tight I would turn that allen screw it would work its way loose and it wasn't striped out. Guess I am just lucky and probably nobody else has had this problem although 2 or 3 other M380 owners have mentioned the same ride height symptoms on their coaches. I sure have learned alot having never had a motorhome with air bags before this one.

The problem is obvious from the pictures. It needs a thirty year coating of grease and oil on every surface. Much too clean and not rusty enough to boot

Old Birds use rods with loops at the top and bottom (mine does, anyway) that are held in place with nuts and bolts. To adjust, BB once added drilled flat bar to one side to lengthen the rod. No slipping is possible.

Default M380 air ride valve linkage

Here are a couple of photos showing what I found on my 2004 M380. Also shown are the new and improved replacement components. The replacement hardware are industrial control components, 100% stainless steel and only about $60 for a complete set of three!

Let me know if anyone wants the info on where to find this hard to find hardware.

That second picture of the socket for the ball looks just like the end of throttle linkage that connects to the carb on my 66 Barracuda. I bet these are a little bigger though.
