Removing running boards... bolt removal challenge

I recently bought a 2004 Tacoma. Love it, but really want the running boards off. First one (driver side) came off no problem. Passenger side has proven much more challenging. But I now (after a good deal of work) have removed 5 of the 6 bolts attaching it. This one just won’t move. I’ve tried PB Blaster (liberally) applied and a blowtorch applied to the bolt numerous times.

it’s definitely a 12mm bolt and at this point either my 12mm socket or the bolt itself is way too stripped. But even my 12mm wrench won’t move it even a smidge.

The faster nut is a v old looking square nut.

I’m hell bent on doing this myself. Any ideas?

 

maybe try hammering on a slightly smaller socket and an impact if you have one

 

Irwin rounded hardware sockets must have for rounded rusty hardware.

4" or 4.5" grinder with cutting disc if your not planning on putting them back on .

 

I can`t recall the last time I used a sawsall working on a vehicle gotta be 10 maybe 15 years.

 

Dremel that sucker off

 

C4, make sure to wear safety glasses

 

Drill out the center of the bolt until you can knock the bolt head off with a hammer and chisel.

 

Impact driver. You need more ugga duggas in your life.

 

I knew someone that could most likely rig things to drop those running boards real sweet.

 

Move to New England. That pesky running board won’t be there come Spring

 

Plenty of meat left on that bolt. Get a 6 point socket and a breaker bar. If you have to, move up to 1/2 drive. Take the 12 point and throw it in the trash.

 

LOL. You must live in S. Cal.

Smoke wrench. You're tickling it with your blowtorch. Get a nice tight flame, and hit the center of the head of the bolt with a perpendicular flame. Get the bolt head actually glowing red. Cool it down with a squirt bottle of water, walk away for 5 minutes. When you come back it will damn near spin out by hand.
