oh crap whats that noise

[07JeepXK]

Just went for a spin and heard the noise too! Interesting i've never heard that before... but I can't remember the last time my Jeep sat outside in that cold, and I normally don't hit the gas that hard to accelerate.

Will have to see if it does it tomorrow morning after sitting in the garage all night.

It's -5 out where I live and my jeep isn't making the noise you guys are talking about. I feel left out lol
