TRD locker motor troubles

Anyone had to deal with diff locker problems? I am on my second (first replaced under warranty by dealer) and need guidance on what to do next...try different make, ARB? other than toyota? Actuator motor is seized up again.

 

get another motor?

 

Do you use the locker often? They are more likely to freeze up when they do not get used often.

Second, are you sure it is the motor or is the motor working but the actuator frozen up (the motor can still trying to be working but the actual gear that locks the differential may be frozen up).

 

Using the locker often is most likely the problem. And it is the actuator, thought I stated that but probably not. I do not really understand this this part too well or the lingo.

 

I had actuator troubles last summer. I fixed it by rebuilding the actuator on a bench and I used for reference. just ignore the part where he redoes the actuator shell with fiberglass.
