So ive always had this high pitch squeak from inside the jeep as i was going over speed bumps or rough road. It drove me NUTS! I tried to all the popular areas, dash board, center console, door jams, back seat and i finally figured it out. It was the seat brackets for the driver/passenger front seats.

So the other day i got in the unbolted the rear brackets. I wanted to do back and then test to see if it squeaks before the front so i could isolate this. So i unbolted just the back, not all the way but just to give the bracket room for me to pick it up some. I used the aircompressor to blow any trash out from under it and then i cut some rectangle pieces of gasket material and slid them under the bracket. One infront of the bolt, one behind. You have to get the bracket really lose to get it up high enough, its like there is a lip where the bolt goes. So after all that i tighten them up and I have not heard a squeak in 3 days of driving! So nice to have a non squeak drive!
