Or so I thought. For the past month or so, my truck would make a squeaking/rubbing sound that appeared to be coming from my drivers seat while driving on rough roads. It sounded a lot like springs that needed to be oiled. Yesterday I decided to detail my interior. I pulled my floor mats and pressure washed them. After a good vacuuming, I reinstalled my mats. That’s when I discovered the source of my squeak. The plastic clips that hold the floor mats in place were rubbing on their mounting posts. Any slight movement of the mat made them squeak. I pulled all my mats and wd40’d the clips from the bottom of the mats, cleaned the excess and reinstalled. All squeaking gone. If I had looked for the source, I would have never looked there. Hope this helps some of you. 30,752 miles on my truck, still going strong!!
