might want to list where your at, as shipping far can make a price out of reason real fast, there NOT light if you get good one's
also might want to say what type of axle you need them for, there not all the same, so, if you find say 10 here and 10 else where, your going to want to be sure there all teh same , so they will work?
I also suggesting calling larger farm scrap yards, they many times have broken down things they will gladly part out, or maybe know where to find some??
another thing to try is honestly, driving about older smaller farm area's
I have seen countless one's laying about no longer in use, as modern farmers don't use them no more , due to changes in farming and equipment they use now!
I'm in PA, so, not sure where you are?
