i was looking at my bactard of a truck this afternoon and thought of something. Don't laugh i haven't put really any thought into this yet. would it be possible to put a grease zerk at some plase in the front hub of say a d-60f so as to facilitate an easy way to grease/push out water from the bearings, kind of like a boat trailer. just wondering if i missed some thing other than the grease going out the axle hole. thanks.
