Method A

WARNING: This page is about a different car, the 2002 Pontiac Sunfire and 2002 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
  1. Use a micrometer in order to measure the balance shaft journal diameter in several places approximately 90 degrees apart. Average the measurements.
  2. Compute the taper and runout to ensure they are within the specification limits.
  3. Use an inside micrometer in order to measure the bearing insert ID. If you are replacing the inserts, measure using the new inserts.
  4. Subtract the bearing measurement from the journal diameter in order to get the clearance. Refer to specifications for allowable limits.
