I'm removing the steering gearbox from my 2004 E-250. I'm trying to remove the gearbox from the frame, but one of the three bolts that mount it to the frame is stuck. I've managed to get the bolt out about halfway, but the more I unscrew it, the tighter it gets. I can't get it out any further with the 15" breaker bar I've been using.
Other than turning really hard, the only thing I've done is spay it with a lot of WD-40.
Other info: The two bolts that I did manage to get out had red-colored thread locking compound on them.
How do I get this bolt out of the gear box?
