Jim R Eastlake , OH September 28, 2015 The 747 landing problem The repair was made in part by using a rear Drum bearing, Door Boot seal and Lip Seal kit. The Front Drum bearing a litter larger than the rear bearing and was needed to completely repair with the washer. I also know now why the tech was wearing gloves. You make it look so easy on the videos but after 10+ years of service things are a little harder. Your videos were very helpful. Thank You, Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
