The job was not too bad using the video. The only problem I had was once the spider arm came out I noticed that the the inner tub bearing had completely deteriorated. This meant that the outer race of the bearing remained seated in the tub. I did a little more research and found other articles where people had the same problem. In order to get the race out I had to take a rotary tool and slowly cut the race. This took me about an hour because I did not want to damage the tub. After slowly cutting and tapping the race with a chisel, it finally came apart. With the race out I was able to follow the rest of the video and put everything back together. It has now been running fine for a month. Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
