what are those little conical things called that go around the bolt? and where can i get some. i seem to have used a little 2 much excessive force to get them off. they wouldnt come off with the penetrating lube. i also heated it up. didnt work. so i took the axle off and flipped it over and to a 8lb. slede hammer to the steering arm. not a good idea. they came off. but two are messed up. the top part is all cut up and bent in (from before with a screwd driver. friends idea. not mine) and i think i need two new ones. also when i took the axle off the front there was a line coming form god knows where to the front diff.? i thought it was a oil line so i got a bucket to put under it. but nothing came out. it looked like there hasnt been anything going through it in a long time. sooo... what is it. i didnt notice it on my half ton so its new to me. noob. could it have anything to do with my auto 4x4 hubs?
