you lucked out with that cheap socket trick,
and .....it might have been the beating on of the socket that enabled to
bolt to turn.
always, always, take a nice solid punch or drift, and give each CV joint
screw several firm sharp 'whacks' with a hammer on the punch or drift.
This has a huge affect in getting the screws 'ready' to unscrew.
It has such a big affect, that after giving a bolt 10 hard sharp whacks, and
feeling that the allen part will strip if I turn to hard, I give it ten more
whacks and try again. and if it still feels like it will strip, then ten
more sharp whacks ....
eventually it will unscrew very nicely.
the other trick I use is to unscrew them with a cold chisel hammered into
the edge of the screw in an 'unscrew' direction.
Need a not too sharp, but properly dull cold chisel, don't want to cut into
the metal, just metal, just make a nice dent in it that the chisel can push
against.
This works really well too, but always give 'em lots of very sharp whacks
( not thuds, whacks ) firsts.
for the outer cv joint screws, I have a 14 inch long cold chisel that works
just great. For the inners, a regular length one.
but whack whack whack first, always.
I read about late model GM head bolts breaking off in the block rather than
unscrewing. The recommended trick was to first give them each several sharp
hard whacks with a big drift and hammer. Huge affect, that trick.
