Glad to hear you got it fixed. That sucks that the sucker exploded like that, I'm going to agree with hydra and say bearing failure because of the whining sound you said. Now what caused the failure is a better question..........

 

Hydra is usually right (except when his visits jack for too long ) so hes probably right. I only said bind because every other transfer case I have heard of exploding was because of bind from not completely disengaging 4wd part time. Also, I'm not completely positive, but I'm pretty sure it can happen to the electronically shifting cases too.

Anyway, glad to see you got it fixed, and I hope this never happens to anyone again.

 

No you shouldn't have to do this because these 2 transfer cases are two different things. There is the NV242 and the NV244, see they are completely different. The NV242 is a PT case, and the NV244 is a AWD case.

I look forward to the pictures, however I still think it was a bearing or a pump personally. Time will tell!
