No it will not affect turning that is why the are called limited slip differentials. But you do not want such an axle up front. The first model of the IH Scout had such a setup.
They only had a 4 cylinder engine they where great on level ground in a straight line but if you try going cross country things get real interesting. The problem with such a setup is steering, but not what you where wondering. If you have both of the front wheels spinning you can't steer it in any direction, and if you are working across a hill if all four wheel loose traction and start to spin you will just slide down the hill, you hope to god your wheels don't catch on something and you roll the thing. With only one wheel spinning up front the wheel that is not slipping will tend to anchor the truck in place so at least you have some control. The Scout was not so bad because it did not have enough power to get you into much trouble, but those souls that dropping V8's into these little short wheel based beasts things got impossible.
