HELP! Broke body bolt

[MSFTMatt]

Just dropped my truck off at another shop, local 4wd shop. They said they can get it done and install the sliders. Finger crossed!

The point of the induction heater is "quickly".
The faster you heat the target - in this case, that bolt, the less time there is to transfer heat to surrounding objects.

It's something I've shown when soldering brush leads to motor frames or ends - a smaller soldering gun will get the job done, but the heat transfer to surrounding parts is too much. Ushing a much higher wattage gun I get the brush lead soldered fine and hardly heat any of the other parts at all.

The induction heater works by concentrating the heat on the target - and doing it quickly, so there's less time for the heat from the bolt to get to the objects it is in contact with. A torch loses a lot of heat to the surrounding things. It works, but you get other parts a lot hotter. Heat transfer takes time, so the faster you get that bolt hot and loose, the less you heat the surrounding parts like that rubber mount.

Ahh so less is more in this case. I don't need to hold it on there as long as i think i need to.

it is a real problem. Its not just ‘some’. But 9. 9 screws. And some pieces of titanium cord (think of baling wire but titanium not steel).

the whole point for the second surgery and removal of hardware was to get rid of a biofilm that was impossible to kill without removing metal. Not to mention my skull bone marrow was infected, didnt even know that was a thing, which required 9+ weeks of central line of some pretty heavy meds to kill it after more skull was cut out. Removal of hardware was to prevent a re-infection. Biofilms almost never go away because there is no blood flow in metal to kill said bacteria. So basically, surgery #2 will probably result in a third at some point, just my assumption.

It took 4 years to finally find a doc (a reconstructive plastic surgeon) that knew what the recurring ulcer on my head was. Everyone thought it was just a pimple conveniently located on top of where the craniotomy was performed. I am lucky the infection did not penetrate the dura and get into my brain, or blood for that matter since the marrow was infected.

it will be interesting though to see what the brain mapping shows from repeated tbi’s

OMG. That's heavy.
Antibiotics and other antibacterials are crazy nasty. The stuff they had me on after the gangrenous gallbladder fun was horrible. It changed my sense of taste, smell, fell, pretty much everything. Bacteria and infection in the area of the head are nothing to mess with. Heck, an abscess on an upper tooth root can kill you. Didn't they catch something in a CBC - like white blood cell counts being elevated, showing infection somewhere?

I looked at the Rock Hard sliders and was ready to buy an induction heater when I decided I didn't feel like working that hard, or risking broken bolts on my new truck.

I may still go that route in the future, when the new wears off. I will be looking at using a temp stick or some other method of monitoring the temp of the bolt and body mount as I heat it up.

You only need to heat enough to warm the locking compound. I figure next time - who cares if it takes all day to get it done.
Be smart - loosen a bolt, do some of the wiring, loosen another, do more of the wiring, loosen another, and so on. You don't have to do all of any part of it at the same exact time.
The best tool for the RSE and other type steps and sliders is patience.

I have learned patience. It took a long time but I've finally learned when it's time to take a break and let the vehicle think about things while I have a cup of coffee.

What temp does the locking compound need? My plan would be to completely clean the compound off of the bolts, and hope there isn't much left on the threads in the body mounts.

...Impact isn't your friend on these body bolts. Been down that road too many times in the past, and also thought, what the @#$ - give it a try. Nope. No good.
If your socket is even up to Menards quality, you aren't going to round these big bolt heads. Ain't gonna happen. But an impact will snap the bolt...

My Campbell Hausfield impact probably doesn't have enough to snap those bolts.

Oh I'm not touching body bolts if i don't have too. And if I do, they are getting PB blaster over night and then cooked within an inch of bubbling paint or melting the bushing. On the brightside, at least Jeep made sure your body wasn't gonna rip off 20k down the road while on a trail. That body ain't going nowhere.

There are some penetrants that are quite a bit better than PB Blaster. Kroil or Liquid Wrench to name a few.

Is there an advantage to going with body mounted sliders vs frame? What a nightmare, I had no idea how big of a bullet I dodged by going with frame mounted sliders. Thank you, White Knuckle, it was a piece of cake compared to the horror stories, done in half a day. Why would anyone knowingly choose this option? I don't mean that in smart ass way, Im honestly asking?

Better clearance than frame mounted.

When I did my RSE's, I didn't break a bolt but I did break loose the flimsy spot welded quasi nut the bolt was loctited to. Passengers side rear. No, I didn't use heat as I had not read about that when I did it. I did use the small back and forth movements and if that nut was more securely attached, I don't think it would have broken loose. It looked like the spot welder missed by a fraction of an inch when that was attached, there was almost no weld in the meat of the flange.

I ended up cutting a square hole under the rear seat, cleaned the paint off then welded the crap out of the "nut" to reattach it. The stitch welded the plate back in. The bolt came out easily after that.

I've never tried Kroil - but will it work on thread locker?

Hahah - yeah, my CP impact wouldn't take loose many of the fasteners on a Jeep.
It might still break 5/16" bolts, but that's about it.
That's why it sits in a cabinet much of the time. It's great for taking off alternator fan/pulley nuts but not a lot more these days.



Generally speaking, related to impact wrenches on long bolts -
The problem with impact wrenches is that if the fastener has any "give" to it, it would be worthless.
These are really long bolts and about all an impact will do is twist the long shank of that body bolt like a spring and then let it unwind, repeat.............
Shorter bolts, maybe, but these are long as shown. With a bar, you can feel the shank wind up, reach its limit, then you are applying force on the locked threads. You can literally feel the bolt spring as you try to loosen it.
My Milwaukee has enough force to break bolts, but these have too much spring to them. An impact only moves a little at a time, then lets off, and hits it again. Not good on loose or long fasteners.

Yeah, even the infectious disease docs were pretty confused as to why the particular pathogens I had were there. I think there were 3 bacteria that infiltrated, likely during initial surgery, one was a form of staph. It was heavy for sure. the first 4 weeks were daily (or maybe twice daily) full doses of diptomycin and vancomycin, then home injections for 9 weeks. But get this, because my detailed oriented brain, I noticed the vials (preloaded syringes actually) were compromised with some type of super tiny (like 0.5mm)...thing. They were coming directly from the medicine makers already contaminated. Fortunately I saw it JUST as that little piece went into the tip of the syringe so I was able to get it out before going into my heart. It took 4 full replacement sets of vials to finally get uncontaminated ones. My best guess is they were 'plugs'. you know sometimes meds are in a glass vial with a rubber stopper and you put the needle through the rubber stopper to pull in meds to be injected. Well I think a bit of that rubber got forced into the needle and thus contaminated the meds. But every spring and 4 sets (7 per set)??? Each syringe was something like $3200 bucks, thankfully the VA took care of that! Who knows how many pieces of rubber are floating around my body that were not caught the first 4 weeks in the ER..... And people wonder why I have trust issues.... Good news is the dura healed well from the initial opening of surgery 1 so that nice lol. It's interesting you mention the tooth. My dad had a coworker with a bad tooth. Instead of getting it fixed he chose to go on his work trip to Texas (from Seattle) and deal with it when he got home. Well he was found dead in the hotel room. Apparently the reduced atmospheric pressure of being in the plane allowed the infection in his tooth to get into his blood, and there was no coming back from that. So I take teeth problems serious now. As for WBC....for me, there was no nothing. All blood tests were normal (except unknown liver problems probably due to contaminates from the desert). I have a super high pain tolerance and medicine does not work on me like it normally does most others. I even did a MRI every 6 months post first surgery for 3 years. it showed some inflammation but everyone thought it was scar tissue. What did I know...I'm not a doctor. Only when it opened and started oozing did I realize something wasn't right. Still took several years of that for someone to finally know what to do. So for several years I was just straight up oozing staph and other bacteria all over the place. Super lucky it didn't spread.

Give Kroil a try sometime. You'll love it.

Anyone with an implant like a hip replacement (me) has to be careful with dentists. I have to take an antibiotic 4 hrs before I go. Any infection that goes to the implant area will grow because of no blood flow in that area. Once that infection gets out into the body. You're in serious trouble.

Had friend go to the dentist. 2 weeks later. Was getting a heart valve replacement. Infection from a absent tooth.

I have never heard about this precaution before. Wow. Did your orthopedic surgeon warn you about the dangers of the dentist? I know many people with implants and have never heard of this....
