[QUOTE="Ditchplains1, post: 1195157, member: 12347"] Ok, here goes...90,500 miles.... Driving for about 40 miles at around 50-60 mph on two lane blacktop primary road when I caught up to a F 350 dually pulling a 28 foot camper travelling about 50 mph. We were both going up a slight but long slope. As I slowed just taking my foot off the gas pedal... A high pitch whine increasing to very loud was heard. I put the tranny in neutral, and pulled to the side. No change with revving the engine in neutral. As I slowed the whine disappeared at about 40 mph. No pulling. Normal 15.3-15.8 mpg's on the trip...300+ miles. The whine recurred several times around the 50 mph speed on smooth roads. Interestingly when going downhill it was impossible to reproduce...either with throttle, brake, or coasting. No whine on rough roads...about 180 of the 300 mile trip. Only able to reproduce it on level or slight uphill grades. No whine with heavy throttle. No change in whine turning wheel left or right. Thoughts? Recently replaced front IWE's...less than 5,000 miles ago. Recent belt tensioner/belt change, 2,000 miles ago. Rear axle bearings? Pinion? Transfer case? Other than the alarming whine no physical changes...no vibrations, normal steering, normal braking, normal acceleration, normal coasting... Thanks in advance.... Eddie [/QUOTE]
