I run welded front diff I'n my 91 yj with a waggy 44 with hubs. And stock style steering set up. With 35" tires.
I love it.
I can steer just fine I'n most condisons. You do lose some turning radious but has not really effected me. As far as street driving I just run 2 wheel.
If I was going to spend the money on a locker it would be a arb hands down.
