6.7L Cummins Forum

The axle fill holes on some 2004 and newer Dodge Truck axles may be located considerably higher that
the actual fluid level. Filling the axle until the fluid comes out of the fill hole will over fill the axle,
which could cause fluid foaming. When checking fluid level or filling a rear axle with fluid, you
must measure distance from the bottom of the fill hole to the actual fluid level. This can easily
be accomplished using a pipe cleaner or piece of wire. Make a 90 degree bend in the wire 2
inches from the end. The wire can then be inserted into the axle fill hole to use as a dipstick.
Measure the distance from the bend to the oil level, The fluid levels for the axles are shown in
the table below.

Hello... New to the site ... trying to find out the fluid capacities for 2007 Ram 2500 6.7 4x4. I have found what fluids to use, but what is the amounts that each component holds?? This would be helpful to know when trying to purchase.

It's in the post above.

I was in the process of researching a current problem with my 07 6.7 which happened recently pulling a 9k load from central Texas to Tulsa. Several of my search terms led me to this forum. Consequently I have joined. I like not reinventing the wheel and find many heads are better than 1.

I agree. So what are you researching?
