The idea is to grasp the driveshaft with your hands and try to rotate it clockwise and counterclockwise, then try to push it up and down, then side to side, then pull it forward and rearward. You're looking for excessive movement or backlash that would indicate a problem with the driveshaft center bearing or U-joint, the transmission output shaft and forward driveshaft flexible coupling (flex disc or giubo), the differential pinion bearings or rear driveshaft flexible coupling, etc.

It sounds like you might be dealing with a common issue in the Jaguar XJ8,
where the torque converter can cause a ticking noise. This can often be
due to wear and tear or issues with the torque converter lockup mechanism.
If you have replaced it with a rebuilt, then it sounds like the rebuilt did not
adequately address the issue.
