"one way" differential
 

Just wondering if anyone has used a one way diff in the front axle of their rig...
I can get one for my WK and have the idea that it will make on road handling improve by acting almost like a open diff and off road still acting like a locked diff.
It will mean only the rear wheels will work for braking and in reverse but this will stop me flipping it over going down steep inclines and the fun of handbrake turns.
thanks for your help

I don't understand how it would operate. Can you give us a link?

A one-way diff works just like a one-way bearing if you think about it like that. When you apply power to turn the diff gear both axles will spin at the same speed just like a locked diff. Under braking or no power input, the spool will free-wheel. This also would mean that in reverse, you'd only have rear-wheel drive since the diff engages in one direction only.

One-way diff in the front are very popular in on-road racing.

that is almost right but the is an individual one way bearing for each side of the axle (each wheel) so when cornering and the wheels are turning at different speeds one wheel (the slower one) will be driven and the other will just be rolling....acting, almost, like a open diff.
so has any one used one for an off road rc and any comments on it???

That is how the twin force was setup stock. most people locked it first thing. It is better for racing but not crawling.

If the one way bearing would hold up to the amount of torqe in a crawler diff, it would work great.

that is how a stock tamiya bruiser or mountaineer is. They have a roller bearing setup in each front wheel hub.
The hilux 4x4 and blazer have that, plus a locki9ng hub to force 4wd
