Ford Mustang (1999-2004) Service Manual: Driveline Angle Inspection

Special Tool(s)

Anglemaster II Driveline Inclinometer 164-R2402 or equivalent

NOTE: An incorrect driveline angle can cause a vibration or shudder.

1. Check the vehicle for evidence or overload or sagging. Check for specified air pressures information in all four tires.

2. Normalize the suspension.

3. Drive the vehicle onto a drive-on hoist or back onto a front-end alignment rack.

4. Inspect the suspension and chassis. Verify that the vehicle curb position ride height is within specification.

  • Measure the curb position ride height with the vehicle empty and all fluids full.

5. Place the Inclinometer flush against the bottom of the driveshaft. After the tool has been held on the driveshaft surface for 5 seconds, push the ALT ZERO button to calibrate to zero degrees.

Remove the tool.

6. To check the pinion angle, rotate the driveshaft so that the rear axle pinion flange yoke ear is parallel to the floor. Remove the U-joint snap ring, then install the special tool. Check and record the pinion angle reading.

  • If the angle is not within specification, repair or adjust to obtain the correct angle. Inspect the rear suspension, rear axle, rear axle mounting or the frame for wear or damage.
