Why Your Rear Door Weatherstrip Rubs Loudly (Causes & Fixes)

Discover the causes and solutions for loud rubbing noises from your rear door weatherstrip. Learn how to diagnose and fix this common issue to enhance your vehicle's comfort.

Potential Causes

Weatherstrip material wear or aging High Probability

Over time rubber weatherstripping loses flexibility, becomes brittle or shrinks, leading to poor sealing and rubbing noise between the door and frame. This degradation increases noise and can allow air and vibration in.

Misaligned weatherstrip Medium Probability

Seal may have shifted out of proper alignment allowing contact or catching against the door edge, causing rubbing or squeaking as the door moves.

Lack of lubrication Medium Probability

Dry rubber surfaces can stick and rub audibly when compressed or sliding against metal surfaces; lubrication can reduce noise.
