I've been upgrading the bushings on my rear drivetrain and differential, and I cannot seem to break free the nuts holding the front of the diff in place!
The part I'm referring to is the rear differential, front mounting point. It connects to the bottom of the diff with two 17mm nuts (those I got loose) and the mount connects to the chassis with a 17mm nut and bolt combo on each side. These are the nuts I can't seem to break free, and I've spent over two and a half hours on these suckers! I've sprayed them with a penetrating spray, I've used a breaker bar, heck I even tried using the breaker bar lifted by my jack! (I have the back of the car up on jack stands, and the rear suspension is unloaded. I've tried lifting the diff with my jack to relieve some of the pressure. I'm at my wits (and arm's) end. I've read that a torch can be used to loosen stubborn nuts, but I'm not sure if that would endanger the factory bushings. I live in Nevada (high desert) so rust isn't a concern, but at this rate I'm wondering if the factory soaked the nuts in Loctite before installing them!
So is fire my next option, or do y'all have any other suggestions for freeing a stubborn nut?
Hope that's enough info.
