Front Drive Shaft Bolts Won't Break Loose! Any Advice?
 
I finally got a chance to get the x5 jacked up and I can not break the bolts loose where the front drive shaft meets the flex disc. Tried penetrating oil overnight, but to no avail. The flex disc is pretty beat up, is it possible the bolts could be bent a bit? Seems unlikely, I know, but anything is possible with my luck. I'm all on my own doing this so I may need to wait til I have some help. I tried a cheater bar, but room is limited. Any advice? Thanks so much!

1/2"-drive ratchet with a telescoping handle works wonders. As does a BFH onto a box end wrench (did I say that out loud? I would never treat my tools like that....)

1/2 inch impact wrench should do the trick.

Heat up the bolt with blow torch. Since your guibo is going to replaced.. 10-20 seconds of high heat should do the trick

I second the blow torch. Never had it fail. Warning: get a heat shield from a hardware store. Plumbing department, used for copper soldering.
