Front skid bolts broke
 
Upgrading from stock front skid and the two bolts from the front end of the skid broke off while I was removing them. Half of both of those bolts are still stuck in the hole. Thoughts on how to remove them? Or should I just try to screw in the new bolts and force the broken bits up through the back end of the hole? Don't really want to drill into them, don't have the equipment. Figured one of you geniuses may have a 'life hack' on how to get broken bolts out.

If they're broken flush there really aren't any other options besides drilling....

if you still have some bolt showing and you've got a welder, you could weld another nut on to the end that would allow you to get it out.

No bolt showing and I don't have a welder anyways. :sobbing:

bolt extractor simple and straight forward

Bolt extractor kits are relatively inexpensive..probably the best route to go.

Bolt extractor, tap set, new bolts and some anti-seize. Extract the old. Tap the hole to clear it of booger’s, then put some anti-seize on the new bolts.

Those bolts seem undersized, and seem to rust and seize very easily, resulting in broken bolts. Use anti-seize any time you remove and replace them.

If using an extractor, I'd hit the top of the holes with some penetrating lube first a day or so beforehand just in case the bolt is seized. Might help things along.

You’re going to need to drill into the broken bolt to use a bolt extractor. If you’re not familiar with the process, here’s an explanation.

Forgot to mention, if half the bolt is still stuck in the hole, remember that bolt is screwed into threads.

By screwing in a new bolt you'll most likely achieve at least one of 2 things:
1) Whatever exposed threads there are that you're using the new bolt to catch on to will be completely stripped (may not be enough exposed threads to get enough bite to do any "pushing")
2) You'll strip the threads the busted bolt are screwed into.

Either way, you're going to end up with stripped threads. You can't just push a threaded bolt out of a hole -you have to rotate/turn it in or out. The new bolt won't magically turn/screw the old/stuck bolt.

Like the other guys said, you probably have 1 of 2 options:
1) Carefully drill through the existing bolt and try not to damage the existing threads. Tap to clean shit up.
2) Extractor bit.

A third option is to bring it to a shop and hope they care as much about your car as you do to not damage the threads. .

Yeah, I've decided to go the extraction kit route. We'll see how this goes. Cross your fingers for me.

I would undecide while you still can.

If those bolts are seized to the point of snapping while loosening then they are really bound. Depending on if there is a lot of rust evident, it's likely that they are cross threaded. Those front bolts are really easy to cross-thread.
Those bolt extractor bits can only stand so much torque and will snap off if over-wrenched.
The extractors are made of hardened steel. Once they break in a bolt you are pretty much done, you're not going to drill that extractor bit out with anything less than a wet diamond. You are down to torch and weld as a fix.

Instead, drill the whole bolt out and repair with a helicoil kit of the original size.
