Hi,
I am new here, I have a 99 TJ, Navy Green/ Tan interior, 35k miles, bought last year and use in summer. Runs great no issues except this. It only happens after driving for 30-40 minutes, and usually on hot days. Mid trip a metal rattling starts, sounds like under the hood. People that hear it say its the fan,but I've looked and its I dont see any wear marks that the fan is hitting. The noise usually happens on the weekend so no shops are open to drive to. The noise does accelerate as I do and when I go in park it stops. Sometimes if I hit the gas and shift into a higher gear the noise stops as the gear shifts. Any idea on what this can be? Its super loud and sounds like the fan is hitting something, but since the noise goes away when the gears shift, usually, sometimes it never stops till I get home. After an hour or so once the car cools down its back to normal with no noise.
