STEERING - On-vehicle Service 37A-7 ON-VEHICLE SERVICE STEERING WHEEL FREE PLAY CHECK 1. With engine running (hydraulic operation), set front wheels straight ahead. 2. Measure the play on steering wheel circumference before wheels start to move when slightly moving steering wheel in both directions. 3. When play exceeds the limit, check for play on steering shaft connection and steering linkage. Correct or replace. 4. If the free play still exceeds the limit value, set steering wheel straight ahead with engine stopped. Load 5 N towards steering wheel circumference and check play. 5. If the play exceeds the standard value, remove steering gear box and check total pinion torque. (Refer to P.37A-17.) STEERING ANGLE CHECK 1. Locate front wheels on turning radius gauge and measure steering angle. Inner wheel 31_45’ ± 1_30’ Outer wheel<For reference> 27_15’ 2. When the angle is not within the standard value, the toe-in is probably incorrect. Adjust the toe-in. Adjust the toe-in by undoing the clip and lock nut, and turning the left and right tie rod turnbuckles by the same amount (in opposite directions). 3. Recheck the steering angle.
