Hello fellow GMCers,

> I planned on introducing myself and my wife, Katherine, on better terms, but unfortunately I’m asking for advice following a breakdown in our recently acquired ‘76 Royale. To make a long story short, we’re in Watkinsville, GA headed black to Ocala, FL and I noticed a slight listing on the right rear suspension during a stop. I pulled the skirt and saw that the inner bottom weld of the support bracket has separated from the bogie and the inner bracket beneath the pin and the entire bracket has rotated about 30 degree outboard - bending, but not breaking the outer weld beneath the rotating pin, if that makes sense.

Thank goodness we have FMCA tow insurance and only have to pay $250 rather than $1000 for a Landoll since it’s not drivable. The tow truck is enroute and I’ll speak with the techs again in the morning. Looks to me like rust along the seam may have weakened the weld?

I would like to see a picture of your 4 bag unit.
I believe it must be the Harrison unit.
Should that be our Quadra bag, we will replace it n/c as we have never had
a failure.

Jim,
I spoke with Shane about his problem and determined that he has one of those four bag setups that used a wobble plate bolted to the bogie that is failing at the hinge.

If that's the case, then I would consider a single-bag replacement setup
like a Sully Bag or Mono Bag or Alex Ferrara's system, all of which are
about half the price of four-bag setups. If the weld broke, then this setup
has a demonstrated weakness and I'm not sure I would ever be comfortable
with it with just a repair.

Nelson,thank you.
As you observed,IT IS NOT THE QUADRA BAG that failed.
We know that on that wobble plate, it cannot handle the twisting of the
boggie arms as it does put tremendous stress on that hinged plate.The weld
sheared.
We recalled all of them and made a deal on the Quadra Bag System.
Others are still selling them by beefing it up or not.

G'day,

Shane sent me the photos and it IS the "flapper" setup and as you can see the weld that holds the vertical piece to the horizontal piece has failed.

http://www.gmcmhphotos.com/photos/g7091-shane-27s-airbag.html

It seems to me that if that part was made from a single piece "C" channel with an ID wide enough for the flapper pivot it would make it much stronger; having noted that the failure mode may transfer to another point.

maybe to late to weigh in, but I had the same problem with the "paddle" system except that mine actually broke. That was an interesting day.

I ended up calling Jeff Sirum who provided a "version 2" replacement with stronger everything. In the course of repairing it, I discovered that the pivot point on the system had NEVER been greased.

Hope that helps.

Shane,

From the thread about your air bag problem, it sounds as if your best
option is a total replacement. Unless something has changed in the past
couple of years, Zeb Jr., at Southland, will offer you his replacement air
bag system. You may choose that, but if you do, you'll probably be in the
small minority of owners. If you choose a single bag system, that from
Alex Ferrara is well thought of and apparently offers ride characteristics
very similar to the original air bags. Then there's the Sully Bag system,
which operates at lower pressure and offers, reportedly, as softer ride.
Your "best", and most expensive, option is the Quad Bag system from Applied
GMC (Jim K). Any of those should serve you well indefinitely.

I would not recommend repairing the "flapper" system -- there've simply
been too many people with too many problems with them. If nothing, else,
the fact that the mounting point on the bogie for the hinge was designed to
do nothing more than secure a flexible rubber&fabric attachment for the
lower center fender skirt.

JMHO,

Thanks Ken,

I appreciate everyone’s advice - just have to decide what system to go with considering all the pros and cons I’ve heard here and read about online (2 page comparison of all airbags, presentations, etc.). I enjoyed the ride quality of the Royale, but don’t have experience driving the other systems to judge what is better for me.

I like a soft, comfortable ride, but don’t necessarily want to sacrifice improved control on the road offered in the newer systems. I’ll continue to research before making up my mind.

Thanks again everyone!,

Shane

Please do not refer to this system as Quadra Bags as we never have
problems with these unit.
Have had people asking us what is the problem with our system or the same
ones that Jim B of Coop sells.

We have one of the first 4 or 5 Quadra Bag systems that JimK sold. This was maybe more than 10 years ago and we have had zero issues. Let’s not get confused with other systems that use 2 or 4 bags.

My personal experience has been with the Quadra bag system. Overbuilt would
be my description of it. Very high quality. I have installed at least 4 of
those systems. Some with drum brakes, and some with disc brakes and
reaction arms. No problems noted.
