welcome...you have 1 or more of the following:
different size tires front to rear,
a flat tire or very underinflated tire,
2 new tires and 2 very worn tires (effectively the same as 2 different sized tires)
front differential gearset is a different ratio then the rear
the front axle actuator cable is "hanging up" or sticking
the vacuum switch on the top of the t-case is sticking.

Those are the ONLY things that I have seen or can think of that can cause this condition.
Let me know what you find or determine please.

Sounds like the cable is not pulling the actuator arm back far enough away from the axle might be the vacuum actuator under battery may be failing...
