One of the bolts that goes through the first and second skid plate and into the frame broke off when I was undoing it. It recently came back from the dealership for an oil change where they would have had to drop the front skid and I believe they just drove the bolt in poorly with an impact or something. Anyway, should I go for the typical easy out method? I'm concerned even if I successfully bite into the thing those threads were seized enough to break the bolt, so will it come out this way? I'm concerned about making the situation worse.

I had some problems with my bolts too. You'll find the nut that is simply tack welded onto the frame will break loose.
I had CrazyJohn weld me in some new nuts, and so far so good. Not sure if this is what you wanted to hear, but there have been many discussion threads about this problem.


For example, your exact situation:

Thanks, I'm going to take a run at it. PB Blaster, left handed drill bit, go slowly, maybe I'll get lucky.

So, since I recently had a hairy situation with the bolt from hell on my alternator, I'll take a crack at a solution.

Solution 1: You can go the usual route of finding a drill bit, a good sharp drill bit and drill the rest of it out with hopes you don't damage the threads. If you damage the threads tap it and re-thread it with one bolt size bigger or see solution 2.

Solution 2: They sell a, often times, not-too-cheap kit called a heli-coil that can replace damaged bolt threads on things like frames and such. I have used them and helped friends use them when we came across stripped out threads. They are pretty handy. Not sure how long they last as I sold the vehicle I had used it on, but it did get the job done. I am not sure as how it would hold up to being loosened and tightened a few times a year, i.e. oil changes.

Sorry to hear about the bad luck. I hope this helps with at least an idea of a solution to start. Good luck!

I am happy to report I was able to successfully remove the broken bolt. I will document what I did in case it is helpful to others. I know this is fairly basic stuff, but some of us are still new to these things and are eager to learn.

First, I drilled out the center of the bolt with a left handed drill bit. My intention was to go ALL the way through the bolt so that when I sprayed it with PB Blaster it would soak in from both sides, but when I got close to breaking through I simply could not drill anymore. I wonder if this is typical?

Next, I went ahead and PB Blasted it and let it soak for 5-10 minutes.

Next, I placed a spiral flute extractor into the drilled out hole and whacked it a few times with a hammer to get it to bite in.

Next, I then slowly turned the extractor by hand counter-clockwise.

I had to repeat the last two steps a couple of times before the bolt broke loose.

With the bolt extracted, I now ran the correct size tap (M8x1.25) through the opening to rehabilitate the threads.

I'm very happy this was successful and didn't require something like welding another nut onto the frame!

Helicoil inserts are for tapped holes in solid metal. There isn't enough metal in this setting to overdrill, tap and insert a coil.

The welded nut solution is really THE solution for this issue. A stock tacked on threaded insert is just not equal to the task of getting beat on the way that skid plates work. The skids go on and off all the time, and in between those maneuvers, they get bent and twisted. You may not even be able to tell how bad it is until you get them off and release the stored up spring force.

In the mall parking lot, maybe those bolts just support the weight of the skid plates, but on the trail, they see a lot of shear.

Most folks just wait till they destroy a hole before they resort to this upgrade and that's not crazy. However, the experience is usually a lot like like this. An argument could be posed for doing this as a preventive measure, under better conditions.

That's why I remove my own skid plates before I take it in for an oil change. They never seem to get it right.

I have to use a large pair of channel locks to loosen my oil filter on the top of my engine. Skid plates, what...

That's right, you only drop skid plates on the trail
