I have a problem with axle leaks on the Dana 60 in my Duster about every other year. I always use "Right Stuff" silicon sealer on the axle flanges as I was sold on this stuff when I saw some things we used this stuff on in the steel mill. Just checking to see approximately how many pints of gear lube you guys are using and if you rearends have a vent on them. Mine does not. If you guys are using a vent were was it installed and where did you buy it from. Thanks.
