Ackerman Steering with Locked Diffs

[Grizzly4x4]

With the steering arms in front of the axles you get the outer wheel to turn with smaller turning radius then the inner wheel which is the opposite of Ackerman steering - not good.

I know, that's why I said to do a behind the axle (BTA) steering conversion on the front axle and leave the tie rod behind the axle on the rear.

locked diff but ackerman concern

i've read many of your posts. you seem intelligent. i think you're falling prey to the engineers' curse of analysis paralysis.
if the inner and outer wheel will not travel the same distance and they are locked in a 1:1 relationship, you'll have unavoidable "crowhopping" caused by this. unless you intend to go fast, this won't have appreciable effect on intended track vs. actual path. you're not going to break parts as a result of it unless you have a much higher traction coefficient than the rest of us. porous aggregates like concrete aren't much different grip than the average sandstone. if the problem you're alluding to has more to do with the device's ability to self-guide, then you're going to need to factor in all the potential changes in all the variables or install sensors to override the original program at runtime to compensate.
