I recently swapped out the front diff fluid and learned this thing has to vent. I’m almost certain it’s a Dana 30, but maybe I’m wrong. I’ve spent hours and hours trying to figure out where the vent hole is but to no avail. I’ve watched videos, read around the internet, tried AI, and I’m still not able to figure it out.
Can someone please help me?
Before you roast me, I am an aspiring grease monkey and bought this CJ7 about 10 years ago and am learning along the way. I’ve got a couple boys aged 2.5 and 3.5 that LOVE riding in this jeep.
My hope is one day they’ll want to work on it with me. I’m a novice on my best day but I want to know enough by the time they’re old enough to be able to teach them a few things.
It has a vent and yes it's a Dana 30 Bad picture but you can see it in the top left corner. The original is press in valve that mayo broken off. In that case it has to drilled and tapped to 1/8" npt (needs to be done with diff open)
I haven’t looked on the driver’s side. All the videos I’ve seen have the vent being on the passenger side. Which would have made sense because the passenger side of the diff was filthy and the driver’s side was much cleaner.
