Lateral Run-Out (Wobble)

Using a dial indicator, measure the lateral run-out or wobble of the rotor. The lateral run-out should not exceed a total indicator reading of 0.010" during one full revolution on properly adjusted wheel bearings. If the lateral run-out exceeds 0.010" total indicator reading, check the mounting surfaces between the rotor and wheel hub, fastener torques, as well as the condition of and adjustment of the wheel bearings.
