1. While driving, make several smooth and then sharp turns of the steering wheel to the right and left in order to check for any difference in steering wheel effort when turning left and right, as well as the presence of a return moment.
2. When the steering wheel is turned 90° and held in this position for several seconds while the vehicle is moving at 35 km/h, after releasing it the steering wheel should return 70° to the neutral position (Fig. 16.6).
Fig. 16.6. Checking the return of the steering wheel to its original position
Note: If the steering wheel is turned very quickly, the effort required to turn it may be increased at first. This is normal, especially when the engine is idling, as the pump output is somewhat reduced.
