1999 TJ Bumper...Can't get the 2 underneath bolts off

I got the 4 top bolts off the bumper of my 1999 TJ. The underneath bolts I can not budge. Any Suggestions on how to get these two torq bolts off.

Well Sir,
If it were me, and I was having that situation, one of the first things I'd try is to smack the heads dead on with a hammer. Any size hammer will do. What happens when you do that is, you "jar" the thread-joint loose. That is, if the threads are binding badly and or, are somewhat fused due to time, moisture and all that, by smacking the head, you send a ripple of vibration through the entire length of the bolt. And that, in many cases, simply breaks the bond and allows for easier removal. Some will say to use all kinds of wazoo penetrating oil. Been trying different kinds of USELESS penetrating oil for decades and none of it works. And I've use all kinds.

Anyway, try the hammer trick. Also, if you have access to it, and haven't tried yet, try using an air impact gun with a Torx bit on it.
Scott

Soak a couple times with PB Blaster, then let sit overnight.

Yep, I have tried the blaster. I have not let it sit over night. I will hit it again in a bit and let it rest over night. Thank you for the help.

Bolt the top back on, to be sure no extra stress of the load on bolts. Heat works.

If all else fails, a 4Ē angle grinder will do the job if you can get to it.

You should use all new bolts anyway.

How big a bolt are you fighting? Breaker bar I can twist off a 1/2 inch fairly easy...

Well just put some heat on it. Did not work. How long do you keep the heat on. I kept it on for about 45 seconds til it started smoking. Put the bar on it again. No luck. Bought an impact driver. Nope. Not a budge.

So you cut the bolt in two, how do you get it out of the frame? It screws into the frame. Thanks for the help.
