recently put milemarker manual hubs on truck. old auto.hubs had a large round spring with bent tabs on the ends so that you could press them together to get the hubs out. the milemarkers dont have the bent ends.how do i get them out. i can get a small pick or screwdriver in there but i can only spin them around.i would like to replace my brake discs in the future but the hubs will have to come out first. naturaly i didnt think about this untill after i installed them. i am sure i can get them out with a lot of tinkering around with small picks,screwdrivers,needlenose pliers,ect. but i dont want to make a day of it when the time comes.
