The least expensive option is most likely to install a Ford traction lok in the rear. You re-use your gears. The pinion doesn't need to be disturbed. You just need to get the backlash and bearing pre-load correct when it is installed. They are durable for most people. If you off road and beat on it or rock climb go with something else.

The rear end has little to no bearing on the binding of the front wheels in 4wd.
Here's why; In our F150s.
With the front axle locked, a turn results in each front wheel following a different [circular] path length.
This results in each wheel rolling a different distance hence related to revolutions they turn.
With the lockup, each wheel fights the other for which one will give up it's traction.
That is the shudder/skipping you feel normally on the inside turn's wheel where some weight has been lifted due to the turn.
The rear traction drive is only pushing this situation along 'with' the front being also driven from the transfer case and being in gear it can't be any other way.
Even if the truck were coasting in 4wd and in neutral, and a turn made without the rear pushing, you would still have the same fight going on between just the front wheels for their traction in a turn.
Don't believe it, try it. I haven't driven with 4wd for the last 10 years and 225k miles and not know differently.
Good luck.

The binding has to do with the front and rear wheels traveling different paths, resulting in different driveline speeds for the front and rear drivelines. There is no differential in the transfer case. Hence, there is no ability for the transfer case to account for differing front and rear axle speeds.
The front is an open differential. Like the rear, it allows differing wheel speeds *on that axle.* Unless you have a front locker, your conclusion is incorrect.
OP, you should look into tires, LSDs, or other solutions. However, your truck is behaving perfectly normally.
