What is Door Hinge?

Most doors have two hinges plus a check strap that holds the door in position. Worn hinge pins make doors drop and hard to close. Hinges are bolted or welded to the pillar. A door that has to be slammed to close may also have a misaligned striker plate.

How it works

Pins rotate in bushings or bearings, carrying the weight of the door.

Why it matters for your car

A sagging door can damage the latch and seal. Grease hinges and check straps regularly with a suitable grease.
