one of the small hoses will continue to leak and needs to be pluged going to the case drain # 6 (3/8 JIC M , the split flange hoses will leak whats in them and stop ( chunk of blue paper towel) , a few pointers , tie the hoses up with some mechanic/tie wire out the way , clean all the dirt from around flanges with air or pressure washing before taking loose and plug up the travel motor inlet ports asap , unless your changing out the unit , use a 1'2 drive deep dish socket on a breaker bar to hold the nut on back of the mounting bolts and an impact on the front side bolt head , if you are removing the sprocket use a pick , air and lubricant to clean the three threaded holes on th sprocket used to push the sprocket off the hub , it's 1/2 nc , a bottoming tap is the way to go to clean the threads before you start , when reinstalling a hub by your self , I put a line up pin (Klien) in a hole on each side and can pick it up and line the holes easily first stab and hold it in with a knee till you get a bolt started , you should clean out the case drain filter while it's down , take care to assembly it back the way it goes as it can be put together a few different ways wrong
