|
|
I was out enjoying this past weekend cruising around in my bug when I began to notice a metallic clunking noise. I figured it was the sway bar bushings and pressed on. When I got home, I crawled under the front and confirmed the sway bar bushings were indeed toast. No big deal.... Then, I noticed the shock was pointing the wrong way. In my haste, I thought it was a bolt that sheared off. So, I drilled it and tried and easy out which shattered. As I hung my head in shame, I looked at the other side and realized it's a nut on a stud which brings me to my question;
What's my next step here? I have a feeling I'm going to be attending to quite a few things in the near future.

Drill it out is the fix, easy peasy. you may then try a bolt extractor. you can heat her up with an oxy acetylene torch to assist. You can run a tap if you nick the threads.
Dont worry this is not too bad. _________________ Sorry About That Chief.

Yes the repair must be made but just as important, do you know why it failed? That bolt may have just been old and fatigued- but it also may have been experiencing a high stress load that if not addressed will cause the replacement bolt to fail prematurely as well. |

Till June 1962, VIN 4 846 835 the bolt had M 10x1,5 thread. From 1962 June till 1965 July the bolt was reinforced to M12 x 1,5. So you have the chance to cut "oversize thread" M12x1,5 and use the later bolt 111 413 403 A.
But there are, were many different bolts.

I am not entirely sure why it failed. Based on the amount of grease, grime and dirt on the knuckles, they are definitely in need of some attention. The steering coupler is cracked as well, so this is an opportunity to fix things that could ultimately cause a lot of issues. I just wasn't ready to dig in this far.
Any suggestions on how to get the broken easy out out? If I pull the beam, I can access it from the body side. I'm probably overthinking this process but that's what I accel in |

I had this happen when I was young. It was frustrating but I made it through.
1. Use a sharp center punch to make a divot dead center of the sheared off bolt/extractor. This is crucial. I have seen a suggestion to use a metal or plastic tube in the area whose OD fits the hole, and whose ID fits your sharpest drill; this helps it stay centered.
2. Buy some new expensive drill bits. Those extractors are hardened and you will need the best.
3. Start with a small bit and keep it straight and centered. Take your time. Getting this right makes the later steps easier.
4. Gradually step up the drill size until you have started to "daylight" the mounting threads inside the mount.
5. Try using a pick to get out the little slivers still in the threads.
6. But a correct size tap, also a good one.
7. Using lots of oil and working half a turn at a time (then backing out and flushing with more oil), work your way through to clean out the threads.
8. Dry, then apply some anti-seize to the new bolt threads, and do not overtorque.
9. Dribble some penetrating oil on the other side and let it work over time to make inevitable removal in the future easier. _________________ Current Fleet:

A correct sized transfer punch is excellent for assuring a center for drilling. The transfer punch is lightly tapped to leave a small mark, then folliw up with a regular centerpunch. Dont hit the transfer punch resl hard as they are delicate and cant readily be resharpened, unlike a regular center punch
Getting the drilled hole dead centered is key for successful busted stud extraction.

This sounds like an exercise in patience. I used an automatic center punch when I started this and think I was off center from the beginning. Crack a beer and get started! Thanks all |

Pull the beam, then drill from other side so as not to be drilling the EZ out you will know when to stop when you hit it, then use a small punch to drive EZ out
back through hole. In my off road days we drilled that hole out to 1/2 in and used a through bolt and nut, stock bolt wouldn't hold up. _________________ 73 Type 181

I'm definitely leaning this way. I appreciate all your suggestions! |
