Hi Holly,

    Your older Foredom CC motor should run smooth. Unplug the handpiece
    from the flex shaft and run the motor to determine if the motor is
    OK and the trouble is in the handpiece. What model handpiece do you
    have? 

    The Foredom 52 is a good handpiece but the front ball bearing wears
    out sooner than average for handpiece bearings. For the
    do-it-yourselfers: You can replace the front bearing yourself
    (Foredom number HP5268, Grainger number 5U526, industry number
    607zz, dimensions 7mm X 19mm X 6mm). The Foredom 52 handpiece can
    last a long time if the collets (two of them in this handpiece) are
    kept clean and adjusted and the bearings are replaced often. Keep the
    slide mechanism clean. Do not over-tighten any of the plastic parts.
    If you want a handpiece that will stand up to daily hard work,
    consider the Faro (same as Foredom 10 or Pfingst AC), the Technique,
    180/00 (same as Grobet Q40) or the Foredom 20.
