2008 Ford F-350 4 x 4. With Dynamic self loader. Truck had a new motor put in from Ford at 300k. Truck does run and drive but has a knocking noice. I have been told it can be pulleys going bad to a rod in motor. I do not know what the issue is but I assume the worst. That is why truck is priced as it is. Lift works perfectly. Truck is sold as is. Thank You
