I took it in for an oil change and the mechanic showed me that the left front tire was "wobbling" about a quarter-inch when moved top and bottom. I had been hearing a bit of noise at highway speeds, especially when turning, but just wrote it off to tire noise. Fortunately they had the part in stock. It came with a new ABS sensor, which he said he hasn't seen before. It so happened that this was the same wheel that I had the ABS sensor replaced about two months ago because the ABS was activating in slow stop-and-go traffic when I'd be riding the brakes. He gave me the two-month old sensor and said to hold onto it in case another one of the existing sensors goes bad. On the ride home I was pleased to notice that the noise I had been hearing was gone.
