BMW 640i xDrive Lubricate Trunk at your home or office.

Our recommendation:

At the first sign of noise or difficulty with opening or closing, lubricant should be applied to the hinges of a trunk door or lid. Before the application, the hinge or hinges should be inspected for damage or mechanical problems. While this is being done, we recommend that other hinges around the exterior of the vehicle be inspected and lubricated as well. If the lubricant on the hinges connecting the truck door or lid to the vehicle has depleted to the point of needing replacement, it is likely that other lubricated parts need servicing as well.
