The title is pretty broad for a squeaking noise. A car can make many squeaking noise throughout its lifetime but this squeaking noise in particular with Nissan Xterra, Pathfinder, and Frontier is unique. It sounds like a wild turkey under the hood when you drive over a bump. What’s the main cause? It’s a simple fix, an uneven rubber bumper under the hood.
You can find 3 of these rubber bumper under the hood at the front edge.
How do you imitate the sound? I noticed while standing outside and shutting the driver or passenger door can replicate the noise.
What’s the cause? Two things. Firstly, It’s the rubber rubbing against the metal frames that’s causing the turkey sound. I think since the rubber gets older, it’ll get harder and the noise will become apparent. Secondly, when driving the vibration is causing the rubber bumper to tighten into the hood giving it more room to move.
How to fix it? If you can, make sure you rotate it counterclockwise so that the rubber bumper comes out a little more so the hood doesn’t move and is tight when you shut it. Make sure you don’t adjust it too much or the hood will not be leveled to the fenders on the side.
Sadly, in my situation the rubber bumper was no longer tightening because it was getting old and warped.
Old vs New Rubber Bumper
Old rubber bumper. It wont stay in position when I adjust it.
New rubber bumper!
I’ve been driving the Xterra for months after installing the rubber hood. It’s safe to say the annoying squeaking noise is gone!
