Pre runner Question

If a Pre-runner has a locking diff, One would have to assume that its the same as the TRD or 4runners locking diffs and only work 5kms or under right.
So I thought to myself if I had that what would be the point, you would have to do the grey wire mod. We just had some snow fall here in the Toronto are and I tell you if I didnt 4x4 I wouldnt be going any where fast. I thought about it yesterday while sitting in traffic going up a slight hill, people in rear wheel drives were all over the place, so even with the diff locked and limited to 5kms where are you going to go, It just make me wonder.

 

No, one would not HAVE to assume, altho assuming what you want to assume is probably the most logical choice.

Just answering your question.
