The only way I know of is to inspect each U-joint.  In your case,
however, if all U-joints were replaced 2 years ago, I wouldn't
expect any of them to be anywhere near needing replacement yet.
I think even on a conservative basis, one can expect a U-joint
to last at least 50,000 miles.  So unless you drive your TR-6
more than 25,000 miles a year I don't think you need worry
about new U-joints for a few more years.

Most U-joints that I have replaced seem to have failed because
of poor or no lubrication.  Such a condition can be made worse
if the U-joint is exposed to the rigors of winter salt on the
road driving.  So again, if your 6 isn't exposed to those conditions
then yoe should expect even longer life from a U-joint.
