Getting that busted bolt out...
Sadly, I didn't discover this issue until the moment I had broken one of these bolts... WTF! Red Loctite? Really?
Red Loctite requires heating to 500 degrees fahrenheit before it will release. WTF were they thinking?
Extraction required a Snap-On (Blue-Point) E-1020 screw extractor set, a Milwaukee 1200W Heat Gun, and removal of the rubber body bushing (be sure to remove the other body bolts before jacking the body up off the frame a bit).
There is a push-nut bolt retainer that you will need to pry off so the heat can get up into the recessed area where the weld-nut is.
There is a scare tactic about "body alignment" the Dealers are spewing about - this is BS.
The 1/4" drill & it's extractor were adequate - it's only necessary to drill out a 5/8" deep hole, no need to drill deeper and risk drilling into the weld nut.
The Heat Gun didn't harm the paint (don't get it too close) and heated the surrounding metal enough (to 500 deg) that the weld nut stayed hot enough, long enough, to extract the bolt.
The Blue-Point Extractor Set is worth it's weight in gold - don't risk your weekend with cheap ass extractors.
