Answers.Body: <p>This question is old, but as noted in the accepted answer (&quot;little different&quot;), it does not illustrate how to use the Limited-Slip gear. With the limited-slip gear, you can even do without the differential. Note that the wheels are on two different axels and the Limited-Slip gear is on the same axle as the opposite normal 24-tooth gear. The Limited-Slip gear does <em>not</em> touch the Crown gear.</p>

Answers.Text: I agree. It is just an answer to this OP here, but not a real differential. As far as I know, a proper differential can't be made with this slip-gear and I'd use worm gears in a Torsen-style solution like the types discussed here: http://www.technicbricks.com/2009/03/tbs-techtips-22-torsen-differential.html

  <p>What's the simplest way to combine the two mechanically such that if you have one motor driving two wheels, they can turn at different speeds (i.e. they aren't locked to each other), but at the same time, they will both receive a reasonable amount of force (i.e. if one wheel does not make contact with the ground, the one that does will still apply some force, as opposed it it not spinning at all and the free-hanging one going at twice the speed)? </p>

  Lego provides a couple of ways for building a differential, such as [this](http://www.brickowl.com/catalog/lego-technic-differential-with-one-gear-28-tooth-bevel-with-open-center-62821):

  If you haven't seen it, [Sariel's limited slip differential](http://sariel.pl/2009/01/limited-slip-differential/) technique might do what you want, but it's a little different than what you are asking for:
  
  ![limited slip differential](https://i.sstatic.net/xf86C.gif)
  
  This setup doesn't provide a clean way of producing a fixed amount of torque to a wheel if it's partner is running free. It instead simply disables the differential if the wheels have been running at different speeds for too long. This isn't a perfect solution, but it is very simple and may work for you depending on exactly what you are trying to accomplish.

  This question is old, but as noted in the accepted answer ("little different"), it does not illustrate how to use the Limited-Slip gear. With the limited-slip gear, you can even do without the differential. Note that the wheels are on two different axels and the Limited-Slip gear is on the same axle as the opposite normal 24-tooth gear. The Limited-Slip gear does *not* touch the Crown gear.

  Of course, it is possible to combine this with a differential:
