Steering Input Test

To carry out this test, proceed as follows:
^ Drive at the speed where the concern occurs, while making sweeping turns in both directions.
^ If the concern goes away or gets worse, the wheel bearings, hubs, U-joints (contained in the axles of 4WD applications), and tire tread wear are all possible sources.
^ Proceed as necessary.
