Lifetime on the shaft but not the labor to install if out of warranty
Install it? It’s one Allen bolt holding it on. Are you saying you payed somebody to do that for you?
Before you make fun of someone you may want to understand what they are saying.
He meant install the shaft. If after 2 years you have to pay labor to install the shaft. Which requires cables, assembly, and armature removal and reinstall all wiring and cables.
