1. What Causes a Car Door to Misalign?

The most common cause of a misaligned car door is wear and tear on the door hinges. According to a study by the University of Michigan’s Transportation Research Institute in 2022, hinge pins and bushings are particularly susceptible to damage. Over time, these components can loosen or corrode, leading to door sag or misalignment. Additional factors include:

Accidents: Even minor collisions can shift the door and its frame.
Heavy Use: Frequent opening and closing, especially on heavier doors, accelerates wear.
Corrosion: Rust weakens the hinges and surrounding metal.
Improper Lubrication: Lack of maintenance causes friction and premature wear.

2. How Can I Diagnose a Misaligned Car Door?

Diagnosing a misaligned car door involves a few simple checks. Start by visually inspecting the door’s alignment with the surrounding body panels. If the door sags or doesn’t sit flush, it’s likely misaligned. Further tests include:

Visual Inspection: Look for gaps, uneven lines, or signs of rubbing.
Lift Test: Open the door slightly and lift the edge. Excessive play in the hinges indicates wear.
Closing Test: Observe how the door closes. Does it require extra force? Does it latch properly?
Sound Test: Listen for squeaking or grinding noises when opening or closing the door.
