Fern-
We visited your coach in Harrington and it is an incredible restoration,
exterior and interior. I hope that you might decide to write some
articles about what you did with the macerator, the generator, and
numerous other devices. There are pictures of your coach published on
the GMCMI Site under the Harrington Rally.
My suggestion on the air bags is to try various pressures until you
reach a satisfactory level that is not so high (maybe 85-90 lbs.), then
readjust your levelers to that height. Mine also wonders, and higher
pressure helps, but does not cure the problem. You may have to convert
to a four-bag or quad-bag system to get the control and ride that you
desire.
Hope to see you and you bride at another rally soon--maybe the Eastern
States Rally at Elkhart Indiana this October.
Bestwishes-

Fern, I too have been chasing a wandering coach. When I purchased i=
t about 5 years ago it had a bad engine so I decided to pull the front clip=
and do a complete rebuild. As you did, I rebuilt or replaced everything! I=
?ve been chasing a wandering problem the whole time. I?ve tried=
everything, different tires, another new steering box, every alignment spe=
c known to man, heavy sway bars front and rear, ect. Some of the things mad=
e a small improvement some did nothing. Returning from a trip last year I t=
hought I heard a clicking noise that may be coming from a front axle. Pulle=
d them out and had them rebuilt for the second time. After reinstalling the=
axles and while I had the front end jacked up I decided to start it and pu=
t it in gear to see if I could see anything amiss. My dad was in the GMC an=
d started it and put it in gear while I very carefully looked under the fro=
nt end, he turned the wheels back and forth and I saw nothing, then I told =
him to shut it down and when he hit the brakes, WOW. The lower control arms=
shifted from the torque of the spinning wheels and the tires toed in at le=
ast an inch. I could see a lot of movement in the lower control arm bushing=
s which I had replaced at the rebuild only about 5,000 miles earlier. I rem=
embered ordering them from my local Autozone and specifically asking for Mo=
og brand, when the came they were in a different box, but they assured me t=
hat they were made by Moog, and only boxed for a different company. I insta=
lled them and never thought about them again until I saw how much give the =
rubber had. I ordered neoprene bushings from Jim K, and that has made the b=
iggest improvement in handling of anything I have done. While chasing my wa=
ndering problem, I had gone to offset Moogs in the top to get more caster a=
nd am trying to decide whether to change them also. Evidently the lower one=
s I installed were too soft for the weight of the GMC. Moogs? I don?t=
know, but they were defiantly allowing a lot of movement. I too thought my=

If you do not start with the A frame gromets, your wasting your time.
There are the easy way to do it and the hard way. Most call me for advice.

Fern -

When you re-built the front-end, did you use the offset bushings to get
more caster. From what I've been told, that is the answer to most wandering
problems. When I bought mine a few years ago, the thing wandered all over the
place. After closer inspection of the front-end components it appeared
that everything was a little worn. So, like most owners, I re-built the
front-end with the guidance of Jim K., Dave Lensi, and others to get the right
components. Well, the wander is gone and it wasn't too painful to the wallet
either.

Fern,

Bonjour mon ami, comment allez vous?

Try setting the rear ride height at 33 inches as measured from the ground to
the wheel well arch in the middle of the bogies just below the beltline.

Don't worry about the pressure c'est ne pa important!

Fern-
You just opened a GMC version of Pandora's Box! This is a very
controversial subject here on the GMC net and at rallys as well. There
are obviously some advantage to both approaches, which the sellers and
some users will be happy to discuss.
I will be happy to provide a personal opinion off net.

Fernand,
There are no offset urethane bushings made at this time. Both major
manufacturers in the US have declined because the bushings would turn
in the sleeves. The rubber ones don't becaused they're bonded to the
sleeves.

HI Brian !  yes i did replace the bushing with offsets I guess

I would be happy to, but my coach is in Ohio and I haven't had the
pleasure of driving it yet!

I'll be bringing her home soon and I intend to be a real pest on this

Since the urathane is not molded to the bushing , the manufacture turned us
down.
You need to stay with thw rubberones.

Fern,
The 4 Bag is the origional design. It was the first .
The Quadrabag or Q Bag is a 2 1/2 generation after the original.
It rides smoother, yet has a firm control,full up and down,will not
bend,easier to mount and have few inovations to make it worth $4oo more.

Forget measuring the air pressure. If your leveling system works, use it to set the correct rear ride height.

The shut off valves are only useful for those people who have leveling system failures. If your leveling system is not operational, then you can set the level temporarily with the shutoff valves by measuring the height as per the manual. This height is going to change as you add or remove items from the coach like people, gas, water, luggage, etc. This is why you eventually need to fix the leveling system so it automatically adjusts for these changes.

Air pressure is only an indicator of coach loading and ride height. What you want is the correct ride height. I occasionally over inflate mine to get over a low clearance in the road. Believe me it really screws up the handling on the highway at higher speeds. Occasionally I'll air it up in town and forget to set it back to auto on the road. I notice the difference immediately when I get up to speed. Luckily on a correctly operating system it is just a flip of a switch or turn of a knob to get it to return to normal.

If you look at the castor, camber, and toe-in with a gauges then change the real height you can see, the rear height affects all three alignments. This is why GM designed the system foe auto correction.

I have found that whenever it is wandering allover it is do to something loose.

Roger-
Having just completed front bearings, hubs, knuckles, ball joints, new
rear disks brakes with hubs and bearings, new Eagles wheels, new BFG
tires, where would you look for something loose?
I appreciate you suggestions-

I have not been watching, but are you running ragwalls at 55lb?
