I need to take out my rear shock but one of the 2 allen bolts that is holding it (the upper one) has been rounded.
I've been told about various ways that such a bolt can be taken out including:
- hammer a torx in and unscrew
- drill a line using a dremel and unscrew with a screwdriver (I don't think the latter will work, the bold is too tight)
- hammer a larger allen key in and unscrew
- drill the hell out of the bolt (I don't want this because I'm afraid I'll damage other parts of the link (bushings etc)
What do you propose for this case?
