Is it normal for lower arm bushings to need replacing after only 62,000 miles? on 2004 Nissan Murano

The problem began after I had the 60,000 mile maintenance check, at which time the tires were rotated and balanced. Since then, I've had the tires balanced again and the front roters replaced. The vibration is not as intense but the steering wheel still quivers when I am driving at 55-70. My tires are still in good shape.
