Watched how to video on how to replace. looked easy enough, video coverd all the details very well. Part was reasonably priced so I thought I'd give it a try. It looked doable for an 80 year old female. Ran into a few little snags but went back to the video and was able to figure it out.m Voila.. Success. It took almost an hour to do including time to go back and review video a few times. If I had to replace another I could do it in 15 minutes. Hardest part was figuring out how to replace the housing back on the flange & pegs correctly.
