High pitched Noise - 2007 Fleetwood Southwind 32VS

My 2007 Southwind 32VS has developed a loud whining noise, coming from under the motorhome when I accelerate. The higher the speed, the louder the noise with the level much higher in the rear. When I lay off the accelerator the noise goes away. F53 chassis. No noticeable issues with transmission, acceleration or power steering. My guess is rear end or drive shaft. Has anyone else experienced this and if so, what was the fix?

Is it proportional to engine speed or you driving speed. Does it get louder at higher RPM or speed. If you are parked do you hear it if you reeve the engine?


I noticed a high pitched sound on mine and it was the exhaust manifold on my DP. Had an exhaust manifold fail on a Class C with 460 and it was more of a ticking sound.

Rear tire whine, rear end ? Check lube level in rear end may help. Check wear/tread on tires.

Unless you only recently bought this RV I am guessing that the noise is new and wasn't always that way? I have heard of a few noise problems with the F53 rear ends that indicated some failure but never experienced it with ours. As I recall the noise was primarily while under load, as yours seems to be. I'd talk to a Ford shop soon.

Pull the rear differencial drain plug or lower bolt and sample the gear oil.

Shinny oil or slivers in it is bad.

The sound increases with speed and significantly subsides when I let up off the gas pedal. At 65mph the sound is excessive. Purrs like a kitten in park.

Thanks for the feedback. My thoughts have been a bearing, driveshaft, or rear gear box issue, with the latter most likely given the noise level is significantly higher in the back than the front. I scheduled a visit with a local shop that specializes in Big Rig and RV repairs. Since the maintenance log that came with the RV doesn't list a tranny flush, I'm gonna have that done as well.

I read about the noise problems with the F53, folks taking the RV to dealers and even Indiana for a look see. Reported as a low, slightly annoying hum. Explained as normal from gear box and not an issue.

My guess is either the differential or a universal joint. Universal joints are pretty easy to replace yourself, the differential, other than a drain and refill, not so much.

If you do take on the universals yourself just be careful and block the wheels in both directions before you start taking the joint apart so the coach stays where you want it to be.

If you do take it somewhere a Ford Commercial truck service center (or an independent shop) is a better option than an RV dealership. All they do day in and day out is chassis stuff as compared to RV shops. Plus if the differential or transmission needs work a truck service center will have the necessary heavy tools and specialized equipment need to do the work. For example to do a full flush on a Ford 5R110W transmission the new fluid should be heated to 160 degrees so the transmission internal thermostat opens otherwise all they can do is a partial exchange.

Those two items have been at the top of my list. I'm taking it to an independent shop whose niche is mechanical repairs and service of big rigs, RV, and heavy equipment.
