Videos made the fix possible.
After watching the repair videos a couple of times, the track and wheel replacement went easily. I was helped with the removal with a little heat. Hair dryer worked well. I did have a difficult time taking the wheel clips off and could not get them back. However, went to Ace hardware and got some "Circlips" with the plyers and it was smooth sailing from there. Great improvement in smoothness, noise reduction, and, of course, pride of a DYI success. Thanks for your support.
