Its hard to say,in the fleet I oversee at that mileage we have done injectors, water pumps, transmissions, transfer cases, complete engines gone bad, brakes, radiators, front and rear axle rebuilds, front suspension and steering rebuilds etc,etc,etc. It goes on and on. Its a truck, it gets used and it wears out. Typically that is about the mileage we dispose of trucks as they start costing way to much in upkeep.
