Jim M Auburn , ME February 27, 2016 Stripped coupler Took the old one off, put the new one on. Agitator arm had to come off first, which was easy since it was flying off during agitation cycle. Found some inner grooves on the arm are worn so maybe will replace whole lot sooner than expected. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
