Not damage from an accident, I have not had any accidents in that car since the LSD was installed at the start of the season. As for driveline shock and wheelhop, I would need more info on what these things are before I can say?
The LSD is a Kaaz brand, and some Google searching has turned up another person that has had a failure like this as well. Looks like the damage on mine, does it not?
