I took my Ex out doing some wheelin' on Saturday and it definitely took a beating on some rocks up and down some steep hills at Tuttle Creek. Everything seems to be fine and normal except one thing. When I go over the large speed bumps at my apartment complex, even at a low speed, I hear this creaking from the front suspension. It almost sounds like something's not lubricated right. The noise doesn't show up in everyday driving, just on the speed bumps. Any ideas??
