I'm in the middle of the same situation withthe pinch bolt and soon, the hubs. I'm trying to talk myself into taking it to a shop to do the struts and boot replacements.

The strut pinch bolt is very hard steel, grade 10.8. I have some "titanium" plated drills from Harbor Freight that are taking forever to cut through this mess. I've already dulled 3-4 bits and I'm not quite done. The metal is brittle so it chips away and can sometimes jam the bit and snap it (1 so far).

I would rather tap it and use an original bolt. If you can't get a good thread, then you can use a through bolt, grade 8 or higher.

If the ball is still spinning in the joint, jack up on the control arm to force the taper back into the knuckle to keep it from rotating. Otherwise, I've had to destroy ends by using a cut off wheel or hacksaw blade to carefully cut the nut end off to get the joint out.
