Im considering a 2020 SR5 Premium with a sunroof. Ive looked at the drawings on the Toyota parts site and I want to understand what happens when you engage and disengage part time 4 wheel drive.

There are 2 motors, one on the transfer case and one the front differential.

When put into 2 wheel high the front drive shaft is disconnected from the transfer case by the first motor.

The second motor disconnects the right wheel drive shaft from the front differential. The left wheel remains connected and when the vehicle moves the front differential will rotate and the front drive shaft (to the transfer case) will also rotate.

Is this correct?
