What Causes the Rattling Noise from the Right Rear Door?

[EliasFitz]

The rattling noise from the right rear door is caused by rust on the car door hinge. Below are the specific reasons: Loose Interior Panel or Audio System: This issue can be identified by shaking the panel by hand or pressing on the noisy area while driving. If the noise stops, this is the cause, and simply tightening the components will resolve it. Rusty Door Hinge: This issue can be heard when opening or closing the door. Cleaning the hinge and applying some grease will fix the problem. Aged Door Seal: If the door seal has not been maintained for a long time, this issue may occur. The best solution is to purchase silicone grease and apply it to the seal. After letting it absorb for an hour, wipe it off for optimal results. Poor Contact in Door Lock Mechanism: If there is a gap or insufficient lubrication, applying grease to the lock mechanism or wrapping waterproof tape around the lock pin a couple of times will resolve the issue.
