Hi, Mark.

It is rare to be able to determine a bad U-joint without removing the shaft 
from the car.  Since you have a 72 it is likley you can remove the shaft 
easily from the car.  it should easily come out toward the front.  The later 
models with the J-type overdrive are much more problematic.  The flange bolts 
are almost inaccessible and there is no room for removal of the shaft.  
Let's hope you car is the former, not the latter.
