I believe it's true, I will take it apart tomorrow to make sure. I did find a few metal shaving on the base of the unit. I looked for parts on the net and saw some were nylon and some metal. However, the Kitchen Aid site sells the part for over $10.00 and Whirlpool (who makes the part) sells it for under $4.00. I'll let you know for future reference, if your interested.
