do you still have the factory locking hubs? if you do reach inside your front wheel and try to turn the axle. Your hubs may still be locking in and you are pulling your front end.

After you disengage the 4WD, do you back up?

I've found a few times after I switch off the ESOF, the front end still binds on a hard turn. I back up about 5' and then go forward. Works okay after that.

Just a thought -

No, make sure your hubs are on auto and vehicle off. Try to turn the axle, if it doesn't turn your hubs are locked in.
