I replaced my Gen1 rack in the driveway a couple months ago. It isn't the smallest task. It wasn't a task I was willing to do twice, so I just replaced it instead of trying to repair it in case my repair didn't work. The core charge was over $200. If it is just the belt, maybe, but this Donut video scared me off on trying to rebuild the rack myself: I'm guessing the Gen2 is easier without the hydraulics, but still. Having to put it all back together to test is a bitch.
