DIAGNOSIS

STEP 1. Check for looseness at the steering shaft coupling section and at the steering wheel linkage.

2) Measure the play on the steering wheel circumference before the wheels start to move when slightly moving the steering wheel in both directions.
Limit: 30 mm (1.2 inch) or less
3) If the free play exceeds the limit value, set the steering wheel straight ahead with the engine stopped. Load approximately 5 N (1.1 pound) towards the steering circumference and check the play.
Standard value (steering wheel play with engine stopped): 16.5 mm (0.65 inch) or less
Q: Does the play exceed the standard value?
YES: Remove the steering gear box and check the total pinion torque. Then go to Step 3.
