I noticed a vibration that seemed to increase over time of about 2 weeks. I took the vehicle into the dealer where they replaced a wheel bearing and recommended I replace the rear tires due to severe cupping. The tires are continental contacts with about 10,000 miles on them and should have lasted the next 5 years. I went to the tire shop where they told me that Ford Focuses are known to have alignment problems and will destroy their tires prematurely. Researching the internet I found 47 such complaints over the years relating exactly to what I experienced. The problem is the rear suspension is cambered in too much at the top and Ford never made the suspension adjustable. Mine measured 1/4 inch difference between the top of the 15 inch rim compared to the bottom. This sits the car on the inside edge of the tire creating the premature wear. Ford must know this problem exists.
The contact owns a 2007 Ford Focus. While driving various speeds, the contact heard a loud noise coming from the front end of the vehicle. She took the vehicle to the dealer and had all four tires replaced. Shortly after the repair, the failure resurfaced accompanied by mild drifting to the right and excessive vibration. She took the vehicle back to the dealer and was informed that the wheel bearings caused the failures. They recommended that an alignment be performed. In addition, all four tires needed to be replaced again. The tire specialist stated that the a component on the vehicle was causing the tires to fail. The vehicle has not been repaired again. The VIN was unknown. The failure mileage was 5,000 and current mileage was 36,000.
