1. Any slight dents, chips,
etc., in either the exciter ring or VSS will create needle waver. Measure
air gap between the VSS and exciter ring. It should be 0.38-0.51mm (0.015-0.020").

per the same ring gear backface runout procedure of the appropriate
model 1996 Powertrain/Drivetrain Service Manual, Section 05-00. Make
sure the exciter ring is mounted correctly to the ring gear. If runout
is more than 0.1mm (0.004"), perform the differential runout check
per the procedure in the appropriate model 1996 Powertrain/Drivetrain
Service Manual, Section 05-02A or 05-02D, to find cause and repair as
needed.
