Driveshaft U-Joints

         Last night I replaced the U-joints in my TR-6 driveshaft.
         It was a struggle even with a U-joint press. They went in but with the 
result is
that when moving the u-joint back and forth it appear very tight and requires 
some extra
pressure. Does anyone have any experience with how tight or loose the u-joint 
should feel
or move.The part is from the Roadster Factory, package label GMB made in Japan.
Would like to hear from anyone who has done this job.
