I have a squeaking noise coming from the area of the outer passenger seat or lower seat belt mount. Sounds like a "cricket chirping" on the highway. About two times per second at 75 mph. Driving me crazy.

 

Might be something in the rail system under the seat , or the passenger side seat belt not all the way against and slack pulled up on the belt.

The other thing to check is the door panel lower connection near the side door armrest, it might need some velcro padding under it.


If its towards the center console. Check the rail system and also make sure the seat adjustment for the slide potion is all the way it, should click in place. One more thing is the seat belt lock itself, it the outside of the seat belt bottom lock rubbing the center console ?

 

It seems to be centered on the lower passenger seat belt mount. I've removed the bolt and the noise stops. I re-installed the bolt with blue locktite and silicone grease on anything that looks like it moves. Noise is back. Getting frustrating.

 

See if its the washer .
