a couple months ago, i was changing my bushings. after putting everything in place, i tried tightenting one of the screws. it just kept on twisting and wouldn't tighten. pulled the screw out and realized the threads from inside the hole all came loose. so its basically just one solid hole now. i read about heli coils and how i'd have to drill a larger hole. i got a little confuse and was wondering if heli coils would really work for my situation. i haven't really had time to fix yet, i've been driving the car like this for a while. i figured the pressure would keep the screw from coming out. since i have a week off i'd like to get it fix...
the screw driver is pointing to where i'm talking about...

this picture is where it actually goes into...

 

man thats a tough one, what i would try do do is use a Timesert. you have to take the old bolt out, tap the hole with a bigger thread. then you put the timesert in and the old bolt treads into that. its like a helicoil but better IMO. also you can locktite the timesert in, and you cant really do that with a helicoil.

actually have you popped that rubber cap from underneath off? you may be able to get in there from the back. maybee use a bolt and nut, or make the hole bigger and weld a new fastner in back of the old one, you know drill the old one bigger and out a new nut on the otherside. then get a bigger rubber gromet to put over the bigger hole?

What is the bolt holding up and what does the bolt insert in to? If I had the choice, I personally would not drive with the current condition. Find the appropriate size helicoil to go with you bolt. You will probably want to measure the hole and measure the drill size to make sure you have enough to tap the hole for a helicoil. More than likely you do, but if you don't I can take you through another process to fix it.
Step 1...Drill the hole using the appropriate drill size for your helicoil tap size
Step 2...Tap your hole using the respective helicoil tap
Step 3...Insert your helicoil using the helicoil installation tool. I would use a self locking helicoil in this circumstance. Cut the helicoil down to size and insert the helicoil a 1/4 to 1/2 turn below flush.
Step 4...remove the tang with the tang breakoff tool...punch will work just fine.
Helicoils are great because they can be replaced over and over so long as the parent threads are good. Contrary to to boosted-dc2 you can apply loctite to a helicoil if you wanted to, but that is going to make it harder to come out if you have to remove it. Let me know if I can explain anything better or if a regular helicoil will not work. There are better ways than just making the hole bigger and welding a fastener, or putting a nut on the other side. Things such as twinserts and even keenserts. Don't be a hack...it will only cost you more in the long run.

so using a helicoil is better than cutting off the old fastner and welding on a new one? hum thats news to me. and the helicoils i am acustom to seeing are the basically for lack of a better description, coiled up wire that you thread into the hole. explain to me how you would locktit that in without locking the bolt? And like i said i would lean more towards a timesert, if i were to do it that way.

whats that rubber cap for? i took it off and could feel the tip of the screw. can i sand the hole opening larger to fit a nut through?

 

you could, thats what i was saying. the best thing to do would be to weld a new one on there.

Yes installing a helicoil is better than welding a new fastener on. Have you ever welded cast? Thats why I wouldn't weld another one on. Cast is not meant to be welded. Your description is right, but if they use coiled up wire on million dollar air craft, I am pretty sure its good for a car. Here is how you put loctite without seizing the bolt. Put a drop or two in the hole...install the helicoil...let it dry and do its job to just the helicoil...then install the bolt. Yahtzee! (stupid 5 post per day)

the unibody of a civic is cast? wow thats news to me. do you even know where that bolt threads into? appearantly not if you think you need to weld to cast to fix that. if your going to waste your 5 post per day on here, at least know what your talking about.

i dont give aircraft mechanics too much credit, ive met a few i wouldnt let work on my ten speed.

Landon

 

Did I not ask what that was? Nobody told me what that was. From as far as I can tell, whatever that screws in to looks cast. I'm not an aircraft mechanic. I know a lot of them, and I wouldn't let them work on my bicycle if I had one. If I were to fix this car at my work, we would install a helicoil. What happens when that nut you welded on strips out? Yeah you can grind it off and weld another one on, but a helicoil takes 5 minutes to remove and replace.

 

JB-HRC3, There is a nut welded on inside the sub frame from the factory. SO wouldn't you think the best way to fix the problem was to re weld the nut on there?
I dont think the op is going to be unbolting and bolting up his lca everyday so i don't know how he could possibly strip it.

Thank you!

how would i got about re-welding the nut? the hole where the rubber piece goes in is really small. barely enough for one finger. there is a loose nut in there though.

it looks to me that you would have to cut a big hole in the bottom of your car which is why id go with a helicoil

 

if you can feel the loose nut, then there is nothing to helicoil anyways. your going to need to take it to someone who knows what there doing. like a said before there probably going to have to make the hole bigger, fix it, and then put a BIGGER gromet in the new hole. make sure you put something over the bare metal so it doesnti rust!!
