Just talked to Oleg and based on my description he thinks it is in the Tcase. When the 4Hi button is pressed it activates an electric motor. His initial thought is that it's a problem with the motor, a sensor, the fork, etc. Shifting into 4 Lo does not work the same as there is no motor it's a mechanical shift and this would explain why it has a problem with the button vs the shifter.

Reading the FSM and evaluating the symptoms with the assumption it only happens in 4 Hi. would imply something related to the actuator circuitry for the electronic motor to move the shift fork to lock the center diff. The FSM doesn't say, but is this motor not used when using the shifter to go into 4LO? In other words, I think 4Hi is an electronic shift (Via actuator motor) after pushing the button. 4LO is a mechanical shift based on the movement of the linkage with the shifter arm. Can someone confirm this?

Took it for another Test drive and it happened in 2WD. Did some research on Yotatech and sounds like a leaking rear axle seal. I took it over to Toy Car Care and they said that is a common problem and they will let me know by the end of the day.

Didn't want to spend the rest of my holiday working on another truck in the cold garage. Besides, I only like to work on my truck.

Yup, it was the rear oil seal. Leaked all over the brake shoes and causes them to bind.

Good deal, and good call searching on YotaTech. I have heard of the axle seal leaking problem, but havn't had it happen to me yet. All my problems have been directly due to ME.

Never heard of the axle seal leak producing the symptoms you described! Goodonya for getting it fixed though. Very easy for unusual symptoms to lead ya down a lonely road, don't ask how I know!!!
