Fender Jaguar tremolo catching on something

[circusinthesky]

I have a Jaguar, and the tremolo arm is getting stuck on the way down. Button in either position. However, when the guitar is sitting on my lap, with the strings up, then it bends all the way down. Stand back up, and it only goes down about half way before it hits something inside. Again, does not matter where the button is set. If I set it on my lap, hold it by the neck and bottom strap button, and rotate the body away from me, then back to me, I can hear something metal flipping back and forth inside the tremolo cavity.

Any thoughts prior to opening it up?

Thanks!

Have you considered the possibility that it is not hitting something where the trem arm is, but actually getting hung up in front of the screws that hold the trem to the body?
Also, does a ground wire run through the trem cavity?

Hmm. Looking at the pics and diagrams here, I don't see it being possible to hit a screw. Looks like all the moving parts are more towards the center. But, even looking at the pics, I don't see anything which is likely to be moving (when I tilt the guitar) enough to allow the trem to fully depress.

Thanks for the reply.

Something may be broken inside.
Only way to tell is to take it apart.

I have a 63 Jag that I have owned since around 73 and they are one quirky guitar.
From the funky bridge to that tremolo.

Many install Mustang bridges and buzz stops to help.

I know yours is a Johnny Marr Jaguar, so that reminded me of seeing some video on Youtube (can't remember if its was Johnny or maybe a NAMM demo), but someone mentioned an insert of some kind (nylon maybe?) in the trem cavity to keep the arm from swinging like the classic version did. Just a thought.
