Propeller Shaft Runout Measurement One-Piece

Tools Required

1. Raise and suitably support the vehicle. Ensure that the drive axle is supported at ride height (vehicle body supported by suspension components) with the wheels free to rotate. Refer to Lifting and Jacking the Vehicle in General Information.
2. Place the transmission in NEUTRAL.
3. Clean the circumference of the propeller shaft of any debris and/or undercoating along the front (1), center (2), and rear (3) positions.
