Hello everyone, I am new to the Forum setting. I am fully retired, Coast Guard as the Chief Engineer (Motor Killer) I was trained in Boat engines and have worked with the vehicles in the Coast Guard. I have just bought my 1st 2010 Nissan Frontier SE, V6. It is a replacement to a 2010 Toyota. I have owned the Frontier for only 1 day. I noticed a sound on the passenger side when accelerating and breaking there is a sound of something sliding back and forth. I pulled the Cabin Filler and I don;t think it has been changed in years. Lots of leaves and dust. Noise still there when stating and stopping. Any suggestions?
