They are back on road again, pushed arm back and bought couple new tires.
Next headache was waiting behind corner, shipping company claims that there must be 14" clearance under belly.
We planned to take airbags off and put threaded rods and pipes over them between arms for shipping.
Any better ideas?

Corley,
Stick around! I'm much dumber than you (proven fact as I compose a series of
future stupid questions to ask the group) and I'm still here. Stay tuned for
some laughs.

Rob,
I apologize, I'm sorry that my responses are not up to your superb
standards. I think it's probably time for me to retire from this forum
since I'm so stupid.

Jim,
I'm not sure that we are measuring at the same point or surface. I'm trying to figure out how to explain this.
The surface I am using is the flat surface that the wheel sits against when it is mounted. This means the straight edge sits crosswise between the bolts and above the center portion of the hub. We are then measuring the difference of two contact points on the wheel mounting surface that are 5" to 8" apart.
Am I making sense here?

Ken, I have a 6 foot level and it just will fit between the lug studs. It
is difficult to see any misalignment on the flanges with it in place,
though.I prefer to use a precision straight edge. I have one that an old
time mill right made for me out of a head rig bandsaw blade. Still straight
after 50 years of use. It always hangs up when not in use. Works perfectly
across the flanges. Very accurate also.

Ken, I was talking about positioning the straight edge like you describe
but spanning both flanges on both wheels. Obviously one would need a long
straightedge to accomplish what I am referring to. USUALLY, only the
forward bogie arm is bent, and most often it is bent towards the frame with
tire wear evident on the outside of the tire. When the straightedge is
placed across one bent like my example, the flange will only contact the
side of the flange towards the rear of the coach while daylight will appear
between the straightedge and front of the flange. I hope my description is
not too confusing. Picture the coach on stands with tires and wheels
removed, with the bogie arms parallel with the floor. The straightedge
narrow edge is held against the mounting flanges on both bogies at the same
time. Side to side distance across the coach is supposed to be the same on
the front and rear bogies. SO, if one holds the straightedge tightly
against the rear bogie flange and against the front flange at the same
time, if in fact they are parallel, the straightedge should make uniform
contact on both flanges. Clear as mud, right?
Hope this helps rather than confuses you.

Nothing wrong with y'all's method, but I prefer this: I bought two strong
round magnets with center holes from Harbor Freight. With two 18" or so
pieces of 5/16" all-thread (just make 'em "long enough"), 8 nuts and
washers, and some little homemade tabs (sort of like drink can tabs but
more sturdy aluminum), I assembled two pedestals. The nuts and washers
secure one end of the all-thread pieces to the magnets and mount a tab on
the opposite end at exactly the same distances from the base of the magnet.
With a pedestal stuck to the frame fore and aft of the rear wheels, a
string between the two tabs is exactly parallel to the frame rail. Measuring
toe of a wheel is a simple matter of measuring from the string to the fore
and aft extremes of the wheel rim.
Writing this took a lot longer than it takes to measure 4 wheels after
you've made the jigs.
JWID,
Ken H.

How about some shutoff valves and just air up the bags.

Rob,
I do not see much difference between the bags and the tires. If the tires have a slow leak they will also have to be aired up upon arrival. A set of shutoff valves and schraders or just schraders would do the trick. If they are worried so much about leaking airbags that they want a solid solution, then what do they want done about the tires?
Maybe fill them with concrete.

Ken,
That would be fine as long as the bags are 100% leak tight and the coach doesn't settle while it's on the ship from Houston to
Finland.

Ken,
You've got a point; Jake could just install a shutoff valve and Schrader valve at the bag inlet and inflate the bags with enough
pressure to get the 14" ground clearance and then shut them off. I assume the 14" inch clearance is because a GMC is a roll on roll
off shipment.
My concerns would be:
1) how much pressure would have to be applied to the bags to raise his GMC enough to meet the 14" ground clearance.
2) the length of time the air bags would be at that pressure.
3) if an air bag did bleed down would anyone on the ship or on the docks when it arrived in Finland know how to air them back up?
4) if an air bag were to blow in transit how would it be repaired on the ship?

Rob M.

for shipping use the ragusa bag replacement pegs. they work great for shipping i bet. easy to put in and take out.
i have one in the place of one of the bad bags i bought from mgm. Ragusa states he knew someone that had the compression
emergency member on both sides and just used them all the time. the air in the tires were all that he had on the back.
It would be good for shipping i bet. Mickey anaheim ca. 77 palm beach.

Forget the shutoff valve. Just disconnect the hose to the bag and install a schrader. Then air it up to the required clearance. Measure the pressure. Once that is done, make a sign and tape it to the sides of the coach over the rear wheels. Make the sign bi-lingual. On each side it should say "Rear Air Suspension." "If the vehicle is low, inflate here (with an arrow pointing inside) to xxx PSI BEFORE moving the vehicle." You could even pack a cheap 12 volt air compressor inside the coach.
If a bag were to blow, it would be no different than a tire blowing. You will have to fix it. You could throw a Ragusa bag eliminator or spare bag (with instructions) inside of the coach if it really bothers you.
I really think we are making more out of this than necessary. Lots of things could go wrong on any vehicle being transported but we do not pack extra parts for all of those possible failures. This is not the first time a GMC has been put on a ship.

Don't expect dockworkers or sailors that have the job to move cargo in
and out as fast as possible to *read* stuff. They won't in 999 of 1000
cases. It is not that they are unable to read english, it is that they
don't want to spend time.

Remove the bags and use a threaded steel rod on each side; adjust the nuts
on the rod until you get the height you want. Height is locked in, so to
speak. Can't go lower as long as the rods are in place.

If you remove the hose to the air bag and screw a schrader valve into the bag, you will bypass all of the air plumbing. It should then hold air. If it doesn't and still leaks down, replace the bag. At 1/2" leak down per day you should be able to tell if you still have a leak after 2 days or so.

When you assume-well you know what happens. That tire could have been from up front and the PO moved it back there to wear out the rest of it's life where less critical. See- I just assumed that whole scenario. And it's really a front end issue by that thought process.
