AXLE MODDING for driven/non driven lift axle
 
this can be used for many different apps.
for my cement truck, i used smaller tires on a driven axle.which we all no u cant do that on a driven axle.it will tare the gears up.
axle this is great for being a lift axle too
what this does is let the diff turn without turning the axles/wheels
1st i had to dremel a small ring arround the axle to fit a e-clip

then i cut the shaft ends off and added bushings/bearings

Interesting. I wonder if there is a way to incorporate a 1-way diff into the Tamiya axle? It would allow the tires to be actually driven forward, but the 1-way action would allow the smaller tires to spin without binding the whole drivetrain. The downside it that the axle wouldn't be engaged when in reverse.

why not just grind down the splines on the inboard end of the shafts? so they're still supported by the diff and bearings like they would normally be but they're not having power transferred through them. seems like it would be much easier.
