I have just received m Caspro-GMC catalog and I get all excited when I
read about the great things their upgrades will do for my '77 Kingsley
... BUT what is the real skinny from those of you who have used some of
their upgrade??
1. 6-speed automatic transmission
2. Electronic "fuzzy logic" shift control
3. Power Drive 3.50
4. 3-bearing front hubs
5. Rear suspension twin stabilizer bars
If you would prefer to remain anonymous to the net I would appreciate a
private e-mail and I will post the results under my name "as told to me
by someone". Thanx.

Gary,

I have the 350 and stabilizers.

Stabilizers have been on for 10+ years, 350 for 30k+, i.e. last tranny
overhaul.

Nothing scientific, but I like the stabilizers as they keep from dragging
the rig's butt coming out of service stations, etc. By coming out carefully
and at an angle I very rarely scrape nowadays. I would assume it also adds
to overall drivability and perhaps helps some against the rut war. For me
the raised butt is sufficient to be happy with it.

The 350 added pep. How much I'm not sure as the difference pre and post
included overhauling the transmission so how much to attribute to each I'm
not sure but it is definately peppier all around.

Bottomline: while I'm not able to offer scientific proof I cam pass on that
I don't regret having purchased/installed the above.

P.S. I tool would be most interested on comments re points 1 & 2 (for next
tranny time).

None of the 5 items are of any interest to me.

Heinz I am trying to understand how the addition of the rear stabilizers
contributed to a raised rear end (the coaches that is)?

Thomas,
The 'stabilizers' are actually torsion bars, I believe, and thereby help to
'lift' the backend. It also limits travel through bounce that one might
experience on occasion. End result is less up/down travel of the coach
itself in dips, etc.

It does not impeede regular 'bag' travel as the stabilizers realy only comes
into play at extremes.

It provides a firmer ride, but not stiff.

It would be interesting to do some comparisons with different coaches over
the same turf.
Perhaps if the westcoast "swap lies" gathering materializes it'll give us
the opportunity.

I just finished a long conversation with Caspro;
RE: 6-speed transmission --- they feel that the beefed-up 3 speed
listed in their new catalog is far and away the best deal. Comes with
the improved shift kit, the reinforced torque converter, the 3.5 power
drive, aluminum pans --- all for $2195.
RE: 3-bearing front hubs --- are actually the identical OEM hub &
bearings plus a third bearing spaced away from the original two. They
have added provision for greasing through a zerk. They have run
x-thousand miles testing and have about 6 out on the highway --- all is
positive so far. Sounds to me since it is and addition of a bearing to
the original two it should be a pretty safe design and I really like the
ability to service the bearings with ease. Price for the complete hub
including brake rotors is $1995 for the pair.

Gary, Did Caspro say the original hub was *not* modified? I looked at
this hub at Marion and(IIRC) the third (ball) bearing goes between the
original (roller) bearings. The outer seal retainer is replaced with
one machined to house the displaced end of the outer roller bearing. I
was told by a recognized authority on GMC hubs and bearings that the hub
must be machined to provide clearance for the additional bearing and
that the designer of this assembly(not Caspro) lost a wheel on his
display coach on the way home from Las Vegas last spring when the hub
separated where it was machined. (I'm not naming any names for obvious
reasons, but IIRC, there was at least one other GMCnetter present when
this conversation took place.)

On the factory hub, the inner race of the inboard bearing is not
completely on the hub - it's supported by the radius on the stub axle.
I don't see any way to add a third bearing without modifying the hub.
No free lunch here.

> They have added provision for greasing through a zerk.

You can modify the original knuckle to do this, but it seems to me an
easy way to blow out the inner grease seal as there's no where for the
excess to go.

> Price for the complete hub including brake rotors is $1995 for the pair.

It's your money, but IMO this is a fix looking for a problem. Service
the bearings properly and you can go a long way on the spare 2 grand.

Thanks Patrick;
The input from the multitudes, most more experienced and knowledgeable
than I, is a great help. I'm sure that I'll find another way to spend
the $2K on the GMC.

Is this the "Wallace Bearing Hub Knuckl" set up ?

Remember one thing about this design. If it used the original bearings plus
an extra bearing installed on the outside, doesn't the knuckle have to be
cut to accept the extra depth of the triple bearing? The originals are
already a tight fit! Something has to be changed in the hub/knuckle.

OK. So what is the difference? In you own opinion! Would you change
to either of these third bearing set ups, or keep the original set up.
I have the tools (Ken Tomas) and the knowledge to take the things apart,
I have done so a couple of times. I have a feeling that this time I
will have to change a side out for wear. I do not just want to spend
any more money unless I get a better bang foir the buck. In the past
when something broke I replaced and upgraded as needed. Appreciate
your response and considerations. Chuck 78 Elaganza, Lompoc, CA.

I think the informal survey that Arch did on the myths of catastrophic
failure of the hubs and bearings etc should tell us all something. we have
to differentiate between needing and upgrade part or wanting it (like to
spend money because we want to be different). The wallace bearings etc in
my opinion are in the wanted column. The bearings that are now being
furnished by cinnabar and Gateway with the .0095" of axial clearance solved
the problems that a few had with the bearings. If everything is within
tolerance in the bubs and knuckles when you install the bearings, and if you
lubricate them the correct way, than they are fine. If you do not do that,
than in my opinion nothing will work for you. Periodic on schedule correct
maintenance is the answer.

And last. I am not convinced that we are not sacrificing something for
these new bearings. If the knuckles and hubs have not been changed in any
way, how do they fit????? Anyone have some pictures that I can see or
technical literature?

Well, I thought my opinion had been pretty clearly expressed, but to
remove all doubt:

I will not use any aftermarket hubs/bearings on my coach. I will buy my
bearings from Cinnabar and use Mobil1 grease. From both my
conversations with numerous long-time GMCers and the reports gathered at
Arch's request, it doesn't appear that the factory setup is a problem if
properly maintained.

Thomas,

I tried to explain this earlier, but I'm not very good with word
pictures. I will try again. The knuckle is not changed. The outer
seal retainer that is stamped steel on the original is replaced with an
extended one turned out of steel. This extended retainer houses the
displaced part of the outer bearing. Ascii art of the retainer follows:

I am not sure what you want me to acll them, but I installed a set of
stabalizers I bought from Don Roberts. He designed them to help prevent the
back end from walking all over the ruts and giving a rough ride. I have had it
for a number of years and believe it has helped greatly in driving through
ruts. I recommened it and made a presentation on how it worked at one of the
rally's. If you have any questions, please email me.

Al,
I would certainly like to hear more about the Don Roberts stabilizers.
My latest consideration is to replace the factory front torsion bar with
the heavier duty one. Then see if the original front bar would be
adaptable to the leading rear bogies, retaining the 2bag system, and
leaving the trailing rears with no anti-sway device.
How are the Roberts units different than something like that or the
other bars
manufactured for the rear?

Tim,
The stablizers go in the back. As best as I understand this process,front and back
wheels track differently. Thus, the back may wander. However, with the
stabalizers, both back wheels will stay together and they won't wander as they did
in the past. The installation takes the front of the back wheels off and you
install a bracket behind them. There is a separate bar that ties the two rails
together. Then the stabalizers are connected from each of the back wheels to the
bar that goes across. Thus the rear wheels are tied together and cannot wander.
They seem to work great, because before I installed them i wandered especially when
going into ruts. If you have any other questions, please let me knw.

Don Roberts can be located at 313-847-8515. As to my presentation, if you
will give me a fax number, I will try to find it tomorrow and fax it to
you.
