Driveline Angle Measurement Preparation

Before measuring universal joint angles, the following must be done;
- Inflate all tires to correct pressure.
- Check the angles in the same loaded or unloaded condition as when the vibration occurred.

Propeller shaft angles change according to the amount of load in the vehicle.
- Check the condition of all suspension components and verify all fasteners are torqued to specifications.
- Check the condition of the engine and transmission mounts and verify all fasteners are torqued to specifications.
