Olson is probably correct. Less expensive wheel pilots are made with less expensive parts. Manufacturers often turn to cheaper parts to keep costs down. Quality suffers more than your checkbook. Sad to say, but you get what you pay for (which is okay, as long as you understand this).
If you've installed the unit yourself, and are confident it functions correctly (smooth operation of the wheel when AP is engaged, not binding or grinding) then the most likely answer is "normal ops".
