Front differential vent

[Car Doc]

I have noticed every time I check my front diff lube there is pressure behind the plug.

Since Scotty Dive has been working on his 2020D front end it reminded me of the add on vent I added to fix that particular issue here is a couple pics for anyone experiencing a similar problem.

A 1/8 pipe barbed hose nipple fits it isn't the exact thread but it goes in fine as far as it needs to go.

I have a slight 90w leak at times from the front diff coming out the drive shaft tube at the front and I believe this will slow it down maybe even stop it time will tell?

I've noticed pressure/ suction on mine as well.If I had a tap (like yours)I would add a vent line. I would have to drill & tap a hole for a vent

Oh heck I just figured all of these had them thats why I started this thread and especially one like yours which is the same tractor as mine.

I sure would have thought they would have drilled and tapped all of them as well engineered as these are overall learned something else new today!
