The rear corner of the sunroof was sticking up about a 1/4 inch. After trying to figure out what was wrong it looked like the plastic cam pieces on that side were not lining up properly and then when trying to open it I hear a loud crack and a couple little plastic pieces come raining down. Has anyone replaced the frame? I can get a used unit from a local junkyard for around $150. Just looks like you remove the pillar trim and headliner then it’s just 8 bolts? Something an average diy mechanic can do in the driveway??
