In installing a new door on a vehicle, what is the correct sequence?

• A. Tighten hinges first
• B. Install the window regulator
• C. Adjust the door to the opening with the striker removed
• D. Paint the door

Answer: (C)

Getting a new door to fit correctly is all about aligning the door in the opening before final fastening and latch work. Removing the striker frees the latch area so you can move and position the door without interference, which is essential for setting proper gaps and flush fit around the entire frame. Hang the door on its hinges in the opening and use shims to adjust its position in three dimensions. Check that the top and bottom gaps are even, that the door edge sits straight with the body line, and that the door closes smoothly without binding. This alignment step ensures the panel sits true to the opening and that the latch will engage properly once everything is tightened. After the door is aligned, reinstall the striker so the latch and striker line up correctly, and then proceed with installing components inside the door (like the window regulator) and finishing steps such as painting. Starting with tightening hinges or installing interior components or paint before proper alignment can lock you into a misfit, making later corrections difficult.
