Component Rotational Speed Worksheet
WARNING: This page does not describe the selected car, but rather 58 other vehicles, including the 2003 Saturn Vue, 2003 Saturn L300, 2003 Saturn Ion 3, 2003 Saturn Ion 2, and 2003 Saturn Ion 1. However, it is still accessible from the selected car via links, so may be relevant.
- Utilize the following worksheet as an aid in calculating the first, second and third order of tire/wheel assembly rotational speed and the first order of driveline (transmission output shaft/rear axle pinion gear) rotational speed related disturbances that may be present in the vehicle. See Fig 1 .
- If after completing the Tire/Wheel Rotation Worksheet, the frequencies calculated DO NOT match the dominant frequency of the disturbance recorded during testing, either recheck the data, or attempt to rematch the figures allowing for 1-5 MPH of speedometer error.
- If the possible tire/wheel assembly and/or driveline/transmission output shaft/rear axle pinion gear rotational speed related frequencies still DO NOT match the dominant frequency of the disturbance, the disturbance is most likely torque/load sensitive.
- If after completing the Tire/Wheel Rotation Worksheet, one of the frequencies calculated does match the dominant frequency of the disturbance, the disturbance is related to the rotation of that component group, tire/wheel assembly or driveline/transmission output shaft/rear axle pinion gear.
