I am wondering if there is a quicker fix or troubleshoot other than trying to get to each diff per below.
On trying to lock the center diff on the big rock, it does not lock and there is a constant buzzing noise. When I go back to unlocked the buzzing noise disappears.
On the front diff, it locks and unlocks fine, but on unlocking it there is a small constant noise, like the end point is off. This goes away once turning the ESC off then on.
On the rear diff, there is no locking or unlocking, and sometimes there is a buzzing noise that is constant when I try to lock, and sometimes there is no noise at all and no movement.
I've read that it could be the diff brain module itself or the actual microservos?
