Help fixing a loose shoulder joint
 

Hey, i got this figuarts vegeta for 100 dollars, so it was pretty cheap considering what they go for, however it has this detail, the left shoulder seems to pop off more than it should and very easily, im thinking its not supposed to be like that, no big deal, but id like to fix it if possible.
the joints squeak as well, but im guessing a drop of wd 40 would fix it?, every joint squeak loudly and is hard

any help would be appreciated.http://i59.tinypic.com/10ro67d.jpghttp://i58.tinypic.com/t8b093.jpg

Its kinda hard to give advice without being able to see whats going on inside the joint. Is it a double ball joint? If so, disassemble the toy as much as possible. Wipe down the male and female joints with a little bit a diluted rubbing alcohol. Once the parts are completely dry, get some super glue and put a small drop on a piece of paper. Finally, take a tooth pick and smear just a tiny dab of super glue all round the surface of the male or female ball joint. You want to have a very thing coat on every surface of the joint that makes contact with the matching piece. Obviously you want to avoid getting any glue into any moving parts that are not disassembled.

You can also pledge floor shine instead of superglue, but I find it to be runny and hard to work with.

heat glue can also be used in socket joints like this. I often use heat glue in loose joints for the neck balls when the hole is larger than the ball that it's going to be sitting on. Just put a drop in, pop the peg in, and move it while the glue cools.
