I have two questions about my TJ's driveshafts. Where does the rear axle vent hose go to on the body or wherever, and why does the front axle not have one? im thinking of blowing the rear one out with some compressed air, and didnt want a bunch of gear oil to end up in my interior or something.
Also, what gear oil do you guys use? 80w-90 or 75w-140? im thinking of going with 75w150 full synthetic GL-5
