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,
