So, the inside-the-frame nut that the bolt that holds the tail bodywork on my bike screws into is stripped loose from the frame. Turning the bolt just turns the nut freely. However, it won't just pull out of the frame, either.

Any suggestions on how to a) get the bolt out so that I can get the bodywork off and b) fix/replace the bolt so that I don't have this problem in the future?

I haven't been able to get a pair of pliers down into it where I could actually hold the thing.

I can post a picture or two of what I'm talking about if that'd help make it clear what I'm babbling about...

 

Can you drill holes through the square tubing of the frame to immobilize the nut? If you drilled very small holes it would not affect the structural integrety of the frame but might be enough space to insert a small nail and cause enough resistance to back the bolt out.

 

Try and get some anti-sieze in there and leave it overnight. I use WD40.

Then perhaps with the help of a friend, a small screwdriver or a slim piece of steel could put some pressure on the nut, while you give it another go.

Just a thought.

Next time put some grease on the threads before you put them in.

 

I JUST had that same problem and I had done just what Doug said. It's nothing you can see. I just drilled a small hole above it in the subframe and and in the process also drilled through the end of what's spinning to create a notch in it. I then stuck a flat screwdriver in there to hold it and was able to unscrew the bolt. No I don't like drilling holes in my **** either but I just wasn't in the mood to be patient and again it's nothing anyone can see...as far as "fixing" it once everything's back together I really don't see having to take it out too often. I'll probably just tighten it the same way and leave it.
