How to Determine if a New Car's Door Has Been Replaced?

[LeLeila]

To determine if a new car's door has been replaced, you can: 1. Feel the opening and closing of the door; a replaced door will be harder to open and close. 2. Check if the gaps on both sides of the door are neat and symmetrical. Observe the door gap on the car's B-pillar; if the gap is straight and relatively large, it indicates the door has been replaced. A car door provides access for the driver and passengers, isolates external interference, and to some extent reduces side impacts to protect the occupants. The method for removing a car door is: 1. Pry off the panel of the window regulator. 2. Disconnect the control wires and remove the adjacent fixing screws. 3. Remove the door handle and pry off the fixing panel of the door switch.
