Quick and easy fix. Might be just a temporary fix, but it only takes a minute to do.
The two circled spots in the picture above, there is something that is like a pocket. Spray some type of silicone lube spray in those pockets. I used WD-40. I sprayed until it started to drip. I recommend placing something on the trunk carpet (i.e. card board) right underneath so you won't dirty it.
