I have 2004 Rubicon with Dana 44's in which I'm changing the fluid. I had no problems with the front however I can only get about 1 1/2 quarts in the rear. I was wondering if it would be possible to put the remaining 16oz in via the vent port? I'm open to any suggestions. I tried putting the rear tires on ramps in an effort to change the angle of the fill hole but this didn't work.
I'm certainly not trying to overfill fill it, I've read several responses of guys dealing with that mess, just trying to get the recommended 2 quarts in.
My driveway sits at a pretty good slope to the street, so I pointed the front end downhill and pulled the rears up onto ramps. This set up allowed me to get an additional 8oz in, leaving me about 8oz shy of the full 2 quarts. Is this something I should leave well enough alone or be concerned that its not full to the recommended specs?
That's my concern Jerry, I'm running a 3" long arm with a 1" body. I have a Tom Woods driveshaft but concerned that the angle of the pumpkin is different then stock not allowing to be filled properly.
I would add the rest through the breather plus some. The bigger issue is the pinion bearings, this is why aftermarket covers come with higher fill holes. With a higher pinion angle you want to have at a minimum the factory recommended amount plus some so that inner pinion bearing is still sitting in oil.
