Jerry M Chicago , IL March 08, 2017 Appliance: Model GE DISHWASHER ZBD1800 Needed to replace apper and lower studs and rollers including guide rail brackets in my dishwasher I watched the video provided on the website and of course, the Guide Rail Bracket video was not available even though that was the hardest to replace. So I just had to move the dishwasher out from the cabinet and then remove the old Brackets by removing the holding screws and reuse the same screws for the new parts. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
