8. Using the Mastertech(R) Series MTS 4000 Driveline Balance and NVH Analyzer (Vetronix), run a second test with a test weight. Using a metal
band, secure the test weight to the end of the driveshaft. The weight should be placed at the end of the driveshaft tube, as close to the tube-to-yoke
weld seam as possible. Mark the location of the test weight on the driveshaft, as shown in the figure below.
