4kq propshaft u-joint part number?

[Mihnea Cotet]

Yup, got one for you I've learnt this summer when I have stripped a CV
joint bolt's head (right, one has resisted a little but not much)...

This is the idea and it worked for me in all kinds of situations, even for
loosening the strut retainer nuts...

Get a triple-square socket set of very good quality and use a socket that's
just the next bigger size than the original hex socket. Force it in with a
hammer (it might need some persuasion for some sizes) and then put the
impact wrench on it, now it should work due to the fact that the
triple-square sockets have more grip than a hex socket. Another idea is to
tap the bolt's head with a hammer before using a socket on it so you
slightly loosen it, this has worked as well for me a few dozen times.


HTH and good luck!
