Anyone else have a noisey passenger seat? Mine creaks if there is a passenger sitting in it. At first, I thought I hadn't tightened the bolts down enough after I took the seat out to run some wires under the carpet... I tightened them and the seat still creaks. It seems like the cause is actually on the seat itself. Haven't had the chance to take the seat out again to see what's going on with it. Wondering if anyone else have the same problem and what was done to fix it.
