  We can rebuild the ball nut core with new seals, snap rings, ball bearings, and recirculation inserts. Core will be returned packed with grease on a mandrel for installation for $299 plus shipping.

  For (2) or more ball nuts, they are $275 each, plus return shipping.

  Our turnaround time for refurbishing these ball nuts is about five business days.

  If you need expedited service, we do offer a one day turn around service. However the availability of this service is dependent on our work load at that moment. In most cases we can make it work for a nominal expedited service charge.

  Please submit our contact form with your contact information, location, and specific needs and we can provide a timeline and estimate.

  Note to maintenance staff on nut / yoke install: Trying to remount the nut while keeping the rotation bearings within the housing is almost impossible due shims wanting to drop down and block the ball nut entry, so just let the bearings get pushed out of the yoke bore when reinstalling the nut, then reinstall the bearings one at a time along with their shims. Once they're all back in, then install the lockring, set preload, tighten the set screws for the lockring, and then the outer retention ring can be installed.
