Just wondering about the effects of the Hubler front hub upgrade on the Stock
GMC torsion bars. The way I see it, the Hubler mod moves the wheels outwards, as
well as the lower ball joint pivot point. this increases the lever effect of the
lower suspension arm on the torsion bar. This would result in additional forces
being appied to the stock torsion bar than wit hthe stock hubs. Is this of any
concern for our 35 year old bars?
Bill Hubler suggests using the 1 ton torsion bars which are shorter and larger
in diameter. This sounds like a good upgrade to include with the hubs, but I
would expect these bars to have an effect on ride quality and stiffness.
While on the Hubler subject, does anyone know if the bearing & seal can be
replaced on the 1-ton hub, or is it necessary to replace the complete hub as an
assy. A web search only shows the complete hubs but in Dan's blog, Jimk shows a
hub partially dismantled to show the bearing size differences. This leads me to
believe that a bearing replacement alone might be possible.
I'd like to hear opinions and experiences on this subject as it is a mod that I
am considering while my coach is in pieces.
Thanks,

I am familiar with the Chev & GMC 1 ton 4 wheel drive front hubs that the
Hubler front end is fashioned after. Yes the bearings can be replaced
separately, greased separately. I had a Chev 4 x 4 with an identical front
end and went 211,000 miles without any bearing issues and only one repack in
that time. If there is such a thing as a Bullet Proof front end system, this
is it. All still available over the counter.

Hi
Here is the Timken catalog that shows the part number and picture for the
GMC front hub.
http://www.timken.com/en-us/products/Documents/BSAC1990andNewerOrder7564.pdf
GMC replacement part number is on Page 103 (SP580310 looks to be the part)
The picture is on page 599 at the lower right. It is an integrated hub,
bearing and mount.
It is interesting that the SP580311 is listed as a replacement for the front
hub on both 4WD and RWD models.

I am sold on the fact that the 1-ton upgrade is the way to go. It has been on my
mind for some time.
I'm still waiting to hear & learn how this upgrade affects the torsion bars. My
only other concern would be availability of replacement lower arms should one
get damaged many years down the road.
This brings up another concern of mine:
As our Suppliers and Coachs age, I am expecting a continual decrease in parts
availability. We already know what it is like to own vehicles with parts that
are no longer made (Wallace hubs, Thermosan, and a long list of Factory parts)
In the best interests of all of us, I sure hope that our specialty suppliers
hand down or share the special production jigs and technical data for the "good
upgrades" to those willing to continue the support needed for survival of our
dinosaurs. To let the info die with it's originator is a shame as it pushes more
and more coaches into retirement.
Thanks,

Thank you Jim. That is why I wanted it. My plan was to get it in 08. But, had a
friend needing a frontend badly. So, he got the only one that was here at the
time. Now it is my turn.
I ran out and asked Alonzo about the bearing replacement but Jim answered faster
and better than I could have, Les.
I visited with Mr. Hubler at length back in 08 at Santa Rosa while he was
replacing a bearing on his. I saw no bearing tool was needed. Sold me right
there and then but I did not tell him that.
I will keep taking pictures and posting them on the blog. I also hope to take a
select few and put them up on Bdub's site for folks that come along later.

So, is their a waiting list for the Hubler front end and if so, how long??

I don't think so now, Jerry. These guys are too busy for me to bother right now. There are almost always 3 people on the phone here at one time. A very busy shop. Donny took today off so that slows things down also.
Back in 08, I believe that was the first Hubler that was installed by Donny and Alonzo. I was the one who broke the news to them why a certain coach was here. I had to run. They were not happy that they were about to install something for the first time. You know how big Donny is, I outran him even with my fused foot. 
Now, if you want one, when you come this month, you better call to make sure all of the parts are here.

Les,
Were finding that the location of the wheel does not seem to cause the
coach to lower bit 3/8 of an inch.
When we do the 2" spacer it is again 1/8-1/4.
The original torsion bar seems to work well and not effect the ride.
Keep in mind, the lower A frame has been rebuilt and the torsion bar
socket is now reinforced on 360 degrees.
There are several things not mentioned or discussed that one need to
know, or face it later.
The bearing comes as a complete unit which we can sell for $200 per side.
If you pay a person to take it apart and screw it up, your wasting your time.

I love mine,especialy the 12" brakes. Now about the cost. IF you need it all done,,,,the Hubler front end is LESS than having original GMC parts. Go to Jims site and add up both, you'll see. Also there have been a bunch of posts on this before. Go to the "list every post" of mine and scroll down,,,you'll find it. My advice,,,,get it,,,,,PL

Thanks Jim, that was about what I expected to hear in terms of how it affects ride height.
Regarding the 1-ton hubs, I agree that it isn't worth it for most people to consider rebuilding them. If is nice to know that they can be taken apart if desired.
Since the hubler front end uses larger and readily available brake discs, has anyone considered using the same discs in the rear with the reaction arm system? I would think it would be more advantageous just due to not needing a specially modified disc for the rear. The additional diameter isn't needed but is still a welcome advantage. The reaction arm system requires custom brackets and spacers, so just some small dimensional changes should be all that is required to accommodate the 1-ton discs in the rear.

Jim,
I've heard but forgotten, does the Hubler kit increase available caster,
even without offset bushings?

Les,
Here's a link to Leigh Harrison's large diameter middle axle brake disk kit:

a specially modified disc for the rear. The additional diameter isn't needed
but is still a welcome advantage. The reaction arm system requires custom
brackets and spacers, so just some small dimensional changes should be all
that is required to accommodate the 1-ton discs in the rear.

Les,
The reactionarm system is so good that there is no real advantage to
using a bigger rotor.
Some havealmost put flat spots on the front tires.
I could not believe what the reaction arm does till we started doing
live tests here.

I would think it would be more advantageous just due to not needing a specially modified disc for the rear. The additional diameter isn't needed but is still a welcome advantage. The reaction arm system requires custom brackets and spacers, so just some small dimensional changes should be all that is required to accommodate the 1-ton discs in the rear.

Rob,
The Harrison big brakes were sort of what I had in mind, but combined with the advantage of the reaction arm.
Most of the reaction arm braking system components are custom made. Even the discs are specially modified for the application, so replacements are only available from a very few sources. From what I can tell, only a few dimensional changes would be required to permit use of an off the shelf disc such as the 1-ton 4x4 front disc that is used in the Hubler upgrade. For some of the same reasons that the Hubler kit is a smart upgrade, I think having an easily obtainable disc for the rear is a worthwhile effort to pursue.
If we are going to discuss this further, it deserves a separate thread so the info doesn't get lost.
