Transfer Case and Front and Rear Differential Service

[Overboost]

Ok gang, this time my research moves to transfer case and differential oil servicing. At 177,000 miles, it is probably overdue.

So my engine mount discussion thread went so well with a lot of our members lending a hand on advice and suggestions, I want to try to get an education on the drive train components and service required.

The differentials are pretty straight forward (I think)
Drain oil from drain plug and fill to fill port? I have read somewhere that there is a specific amount of oil and will not fill to fill port or is it fill to fill port?

Secondly is the x-drive transfer case (4/04 build LCI)
The drain and fill is the same question as differentials. Specific amount or fill to fill port?

Most important is the reset of the transfer case after oil service.

I need to know what tools are required to reset the adaptations. From my research, I see DIS is the most common but of coarse I don't have that tool. Is this possible with INPA or Pa Soft 1.4 (I have those) or even a Foxwell tool that I am not opposed to buying.


Also, what oils do you recommend? I know the X-Drive requires or suggests the BMW Power Divider Oil and Redline seems to be the most popular for the diffs but any suggestions or advice is welcomed, like I said you guys helped me immensely with my engine mount thread. TIA
