Whistling
At exactly 25 mph, my 05 ranger 4.0 4x4 with 44k has this slight yet escalating whistle that turns into more of a slight moaning noise as the speed increases. If the speed is kept at a constant 25 mph, it's a combination of whistling/moaning. When the truck gets to around 65-70 mph, it seems like i'm really forcing the truck to get further up there in speed, and it feels like something is slowing the truck down. The truck also doesn't seem to coast too smoothly. Everything has been maintained and just about all of the front suspension components have been changed except for wheel bearings and axles. Any ideas? my thoughts are it's either wheel bearings or something is wrong in the differential?
