Steering: Testing and Inspection






DIAGNOSIS AND TESTING - STEERING DIAGNOSIS CHARTS

NOTE: There are two diagnosis charts following that cover PERFORMANCE ISSUES and NOISE, VIBRATION AND HARSHNESS (NVH) ISSUES.

PERFORMANCE ISSUES













NOISE, VIBRATION AND HARSHNESS (NVH) ISSUES









NOTE: * Slight noise is normal in the EPS system. There is only a problem if the noise is very intense or there are strong vibrations in the steering wheel that cannot be attributed to other steering components.

NOTE: ** A light clunk may be felt or heard during steering wheel reversal while vehicle is stationary. This results from internal steering gear rack movement at the bushings and in no way affects the performance of the steering system. This movement may be felt in the steering components during steering wheel reversal.
