this probably isnt the smartest question but im a newbie ive only been wheeling and working on 4x4's for alittle while and i had a question about hubs. i have a dana 60 with warn premuim hubs. do they seal up real good in mud and water? im asking because its going from my dd to my offroad truck and id like to try and get the majority of the bugs out now. and what r drive flanges ive heard of them but i dont know what they are. thanks alot for any input.
