Incase you didnt see my "Drivetrain Vibrations" thread, I spent lots of time looking everywhere BUT my U-joints. By the time I serviced them, it was too late and the foward-most U-joint gave out. I was told that I got lucky, because if the joint to the TC would have gone, the shaft would have done a lot more damage. It only made a little knick on the oil pan since I IMMIDIATELY let off the gas and pulled over when it went.
Lesson: if there aren't any obvious origins for drivetrain vibrations that can be easily diagnosed (ie. wheel bearings, flex coupler, alignment) chances are your U-joints are in need of service or replacement.
DO NOT, I repeat, DO NOT allow to any extended amount of time to pass after the vibrations begin. GET THEM SERVICED or REPLACED!
So I have a temporary shaft on now since I found this to be a great oportunity to make a repair-slash-upgrade... GBR Double Cardon shaft on the way
