What Causes the Squeaking Sound When Opening and Closing the Grand Cherokee Doors?

[DelAlexander]

The reason for the door noise is the squeaking sound from the hinges due to prolonged use. Below are specific explanations regarding the squeaking sound from the Grand Cherokee doors: 1. Regular maintenance of door hinges is necessary: The door and the body are connected via hinges. To ensure the pulley remains smooth and quiet for a long time, it is essential to apply lubricating oil for maintenance every 2-3 months. 2. Most components of the window regulator and door lock mechanism are located inside the door, which is also a common area for abnormal noises: To eliminate door noise, the inner door panel must be removed to inspect whether internal components are malfunctioning, whether screws are loose, and whether movements are smooth.
