QD-I Question

[madrock]

Sorry for all of the newb questions. My 4WD Commander has the 3.7L engine which I presume is the QD-I system. From my research, that means I have:

C200F - Front Axle (1.5 quarts)
C213R - Rear Axle (2.5 quarts)
NV140 - Transfer Case (1.4 pints or ~ 0.75 quart)

Is that correct?

I found conflicting info regarding the need to use a friction modifier. Is it needed, especially if I use Mobil 1? If so, do I put that in before the gear lube? I also read about needing a gasket when changing the differential fluids. Is that necessary, or can I wrap the threads in teflon tape?

Thanks!
