Problem: I'm working on the assembly of this LEGO Porsche 911 but I've run into a frustrating issue where this grey axle won't stay secure in the designated hole. It feels extremely loose because the surrounding frame seems slightly off. Looking at the current state of my build in the photo, can you identify which specific part I have misplaced that is causing this misalignment? Please check the manual and explain the error so I can fix the structural integrity."
Answer: The vertical connector is too long, which prevents the parallel beams from aligning. Use a shorter connector to restore parallelism so the axle can fit securely.
