I did. That didn't do anything for me. (Not likely the steering angle sensor.)

In fact/also, the fault codes relate to the transfer case and servo. There's a cheap replacement for a worn gear in the servo, which I'm going to try.

But if that doesn't work, I just wonder, for strategy purposes, if there's a way to know whether the transfer case is the culprit, just the servo, or both.

If it's the servo motor, then it's $800 or thereabouts for the part. And I think I can handle the job myself.

But if it's the transfer case itself, then I'm hesitant to fix. Dealer quoted $4200.

In short, I don't want to spend $800 on a new servo if the problem is the transfer case. (If the dealer is already going to beat me up, I don't want to be punching myself in the face too.)
