7. Mark and number the shaft six inches from the pinion yoke end at four positions 90 degrees apart.
8. Run and accelerate vehicle until vibration occurs. Note the intensity and speed the vibration occurred. Stop the engine.
9. Install a screw clamp at position (1).
10. Start engine and check vibration. If there is little or no change move the clamp to the next positions. Repeat the vibration test.
NOTE: If there is no difference in vibration at this positions, the vibration may not be the propeller shaft.
11. If vibration decreased, install a second clamp (1) and repeat the test.
12. If additional clamp causes an additional vibration, separate the clamps 1/2 inch (1) above and below the mark. Repeat the vibration test.
13. Increase distance between the clamp screws (1) (2) and repeat test, until the least amount of vibration is noticed. Bend the slack end of the clamps
so screws will not loosen.
14. If vibration remains unacceptable, repeat the procedure to the front end of the propeller shaft.
15. Install wheels and lower vehicle.
