Undercarriage noise--possibly driveshaft?

Hello all, I am brand new here and a new Subaru owner. I have a 1991 Legacy L AWD wagon. It is an automatic with 225k miles. I am having a problem that I hope you can help with.

The car makes a loud clanging noise from underneath while driving. My friend and I put the car up on 4 jack stands and accelerated up to 60+ mph. The noise definitely sounds like it is coming from the driveshaft. I can't tell if it's the front or middle u joints (if that's what you call them on a Subaru).

Has anyone else had this problem? How likely is the driveshaft to fail if I continue to drive it like this?

I was going to rotate the drive shaft at the middle joint, but of course, I don't have the proper tools. I can't seem to get a 12mm socket on the bolt head side, nor do I have a slim enough wrench.

I hope the experience of the members here can help me as I am planning at 1200 mile trip with this car this Thursday.

Thanks,
Dale

is it doing it all the time or just when you turn? if its turning only you may be experiancing torque bind ( do a search on it, there is a ton of information on it out there )

also check the carrier bearing ( where the driveshaft bolts to the tunnel about midway ) if that is bad it could do what you are talking about.
