It was easy. Just unscrewed the old one from inside the door and screwed in the new one. For the model # JBP78W0B1WW you have to order 2 end caps MFG(MFG # WB07K10043 and handle MFG # WB15X10018 ). Read another review and it was very helpful in ordering the right parts. Thank you for that review. And the parts came in a timely fashion (2 days).
