Whiny Ford truck
The first thing you need to do is determine where the noise is coming from. The Ford F-Series has had two distinct problems. The first is a problem internal to the transmission or if you are lucky a clogged transmission filter may be the problem. The second is with a noisy rear differential. Once you can determine where the noise is coming from then you can determine what needs to be repaired. In just about any case it will be expensive.
