Ford F-450 owners have reported 2 problems related to engine rattling and whining sounds (under the engine and engine cooling category). The most recently reported issues are listed below.
Investigation needs to be done on 2008 Ford f450sd 6. 4l trucks on the bolts that are used in the engine compartment for the exhausts. Have a bolt that broke that is now causing a whistling sound under acceleration and exhaust fumes to escape. On the driver side four other bolts have broken off in the head unit that will require for the engine or cab to be removed in order to replace the bolts. The repair facility my truck is located has four other 6. 4l Ford super duty trucks sitting their for the same repairs. Seems to me there is an issue with the type of studs and bolts the manufacturer used. Recall needs to be issued to fix this issue. The other trucks were f250, f350, and f450 super duty 6. 4l turbo diesel. The exhaust fumes is definitely a safety hazard.

Ford needs to issue a recall for faulty bolts in the engine compartment. One bolt broken off on the passenger side that deals with the exhaust causing a whistling sound under acceleration. Four bolts broke off on the driver side that go into the head of the engine block. Impossible to gain access to these bolts unless you pull the engine out in order to replace. Ford needs to held accountable for these faulty hardware and replace this at no cost to the owner of the vehicle.
