Lately when I have been driving, the steering has felt slightly loose. Any rut in the road pulls it hard. Also, I get vibration on the front wheels normally at about 75-80mph, but somedays it 60mph and somedays it vibrates worse. It feels like something it loose on the front suspension. My gut tells me its more than just a tire balance. Any ideas?
