Fig 1: Measuring Shaft End Play

Measure the shaft end play using the following procedure:
1. Install the J 8001 or the equivalent on the axle tube end.
  The plunger of the indicator must be at a right angle to the axle flange.
2. Move the shaft back and forth and read the end play.
  The correct end play is 0.03-0.51 mm (0.001-0.020 in).
3. If the end play is incorrect, install a thicker or thinner shim as needed in order to bring the end play into the specified range.
