Removing Front Axels

[Louis-Alain Richard]

Dumb question : did you use the triple-square socket or the regular
allen-head ? If I remember well, these are triple-square, like a Torx but
with twelve points instead. A regular internal hex socket will indeed ruin
the fine valleys very quickly...

Triple square sockets : I use a set like these for VAG head bolts and CV
joints bolts

These ARE the internal star bolts.  I have used penetrant. Will wait a day
or so with occasional tapping to see what this might do.

RE Vice Grips. I've certainly had success using Vice Grips on hex head bolts
but.....If I wasn't able to budge one while nearly stripping the internal
star I can't see how I could muscle enough force using vise grips on the
smooth exterior...or am I missing something?

Being the third owner I'm wondering if someone might have used Loctite on
them out of some misplace sense of safety.

...and the Irwin star extractor seems suited to hex heads ..not internal
stars......comments pls.
