If you have a WJ Jeep Grand Cherokee, especially one with QuadraDrive, the type of fluid you use and the procedure for servicing the axles and transfer case are very important. Today we walk through the process of doing a fluid service on the front and rear axles as well as the NV247 transfer case on this 2004 Quadra Drive equipped WJ.

Fluid:
75W-140 Synthetic (This is the fluid spec for the vast majority of WJ's, including Dana 30, 35C, and 44A axles - Note that SOME 1999 WJ's may have 80w90 spec'ed, and others may state 75w140 for towing. All of mine which were 2004 model year have always used 75w140)

1 Gallon will service both axles with fluid leftover.
