An eddy current probe with a probe body having at least one eddy current coil is centered on a probe shaft by a pod with a plurality of replaceable centering feet which allows abraded centering feet to be replaced while the balance of the probe is retained and reused. Typically, the probe body is sandwiched between a pair of such centering pods. The replaceable pods comprise matching halves, divided longitudinally, that fit together over the shaft. Each of the centering pods is retained against the body probe by means of a retaining cap threaded on the probe shaft against the joined pod halves urging the pod against the probe body. The pod extends into an annular trepan in the probe body to secure the pods at that end. A face within the retaining cap normal to the shaft or slanted acutely toward the probe and overhanging the pod retains the pod in position around the shaft at the retaining cap end.
