how do i get the u joints out. i drilled out the plastic plug things and i have it in the vice. i cant push them out. do all cvs hav that little ball thing in them? just wondering because i want to see if its possible to put the front cv on my rear driveshaft. i need the extra length it gives. it looks like the u joints in the cv are the same size as the ones in me rear driveshaft already.
