I'm brashly assuming that these are hubs for the front wheels (please
correct me if I'm wrong).
Does anybody make good-quality lockable/unlockable hub/axle
combinations for the middle/rear axles? An article in MV Mag a while
back stated that disconnecting one set of wheels made the truck drive
a lot better on pavement, by eliminating drivetrain wind-up. On the
other hand, I think some folks have said that doing that can make the
truck get stuck a lot easier, due to the reduced traction. It seems to
me that having switchable hubs on one of the rear axles might offer
the best of both worlds.
An air-switchable clutch between the middle/rear axles might be even
nicer, but I figure that would be much more difficult and expensive to
make.
I balanced out the tire circumferences on each dual (within 1/4") and
the average circumference between the two rear axles (within 1/2") as
well as I could, but my truck still makes visible tire tracks on
concrete. That suggests to me that the tires are scrubbing, and I have
a hunch that disconnecting one of the axles might greatly reduce that,
but I don't want to give up the ability to have all wheels driving
under less-than-ideal conditions.
Opinions?
