Rear diff and transfer case fluid change
Hey All:
I just picked up a 2001 SCREW 4x4 with a 5.4 motor.
I don't have any maintenance records, so I want to replace as many of the fluids as possible before winter. So far I have just replaced the tranny fluid and engine oil.
My areas of concern are a transfer case flush, and a rear diff fluid change. I looked in the owner's guide and can't find anything regarding capacaties. I would like to use one of these Mobil1 products :

..but I don't know how much I need to buy to perform this procedure.
Anyone out there know which Mobil1 product I should use, and how much of it I need??
Thanks for your help,
Jake's Dad

2 quarts for the trans case is correct and 3 quarts for the rear is what i needed check and see if you need friction mod additive for the rear i had to buy it mobil 1 itsnt my oil of choice but i have heard its good i hear many people suggesting royal purple and i have seen a few posts on here about it i am a amsoil guy but everyone has there preferences if you are taking the time to do the rear i would do the front also it takes 2 quarts

Going to do this myself. Rear diff. takes 75w140, 2.6L(5.5pints), front axle takes 75w90, 2.0L(3.7 pints), transfer case takes 2 quarts of MERCON ATF 4x4 vehicles according to the Owners Guide I have. If u can't find an Owners Guide for ur truck, buy a Haynes Repair Manual, it helps. It does not show how to change the transfer case oil though.

2 quarts. About 3 weeks ago i changed my front differential and rear differential with Royal Purple gear oil, engine oil with pennzoil ultra class synthetic, transfer case with royal purple ATF, K&N oil filter, cleaned my K&N air filter, and added 3 bottles of Lucas Fuel Injector cleaner.
