The rear left side of the lid pinches against the rear left side of the top case causing a pop or clicking sound when the lid is opened. After looking through your 41 Step-by-step Guides I have this question. Is this a Left Hinge replacement or can this be adjusted in some way? The top is out of alignment about 1/16 of an inch to the right when closed. MacBook 2.1 (5HS)

OK, changed the left hinge and that seems to have worked. Cheers!
