Richard, I'm not sure from your description, as to whether you feel  
it is in the front end or the rear drive shaft.

Were the wheels/tires balanced on the vehicle? Some cars really  
require this to get it 'perfect'. A lot of shops do not know how to  
balance wheels/tires properly, so I suggest finding a specialty shop  
that REALLY knows what they are doing, if you haven't previously done  
so.

Failing that, it may be your drive shaft, and it may need to be  
balanced. Here are a couple of jobs that show how to do this. There  
is also job 41-080 in the Service Manual if you need it.

Regards,
Steve
