Parts Used:

1. Removed the rear wheel

4. Called eReplacement
5. Operator was VERY helpful and courteous.
6. Placed order
7. Order arrived in 3 days

The new wheel has new \"cogs\" for self propelled, so I simpl y replaced the wheel. I am not a \"do it yourself person\", but this was very easy to do. I was very impressed with eReplacement\'s ease of ordering, courteous and fast service. Would recommend them highly. No special tools were required. Just a socket wrench.
