I got bored today, so i attempted to pull my roof rack off. Two of the Torx bolts cross threaded during install (at the factory) then stripped completely, basically spinning freely after some twisting. The rest will be getting replaced soon due to rust.
Until I can source some rubber plugs for the holes, the bolts are back in their holes, screwed all the way in.
My advice to everyone with wagons and roof racks, periodically remove them and oil them, or even better, use anti-seize on them and then never worry about them locking in place like mine did, if you ever change your mind and decide to remove them.
