Do you got Car, Bike, Bicycle?? Anything?? If not then Truck, Tractor must be??
What you do if Wheel Barring got issue? You condemn that Car, Bike, Bicycle, Truck or Tractor?? Or replace Barring?? Now if Car's Rim or Alloy got issue then you replace it or purchase New Car??
Have traveled BEST in Pune & Mumbai long back & use to wonder how come engine sounds brand new but Bus body isnt seem that new. I guess they replace old engine with new one under same body!!
