I have a 2002 mustang 6cyl and I have a drive shaft issue. It all started out driving on the hwy i was going about 65 going down hill and it started vibrating. I started to slow down and the vibration disappeared. But once I started going up hill and speeding up it started getting worse. I had pulled over and found that the drive shaft was cherry red!! I had it towed back to my house and once I got it up off it's wheels i could hear some rough metal on metal noise. Could it possibly be my Ujoints or the bearings? I'm strapped for cash and would like to attempt to fix it my self. Any suggestions???

What part of it was turning red?
