Good To Know

Q: How to tell when door wedges need replacing? A: If there is rattling from the doors while driving, or if the door droops slightly when latching, the wedges are likely worn.

Q: Does this replacement require modifications to the door frame? A: No, these are designed to mount directly into the factory positions using the existing hardware.
