Motor Whine

[meighkee]

Greetings.

Am considering purchasing a 2005 Georgie Boy Landau 2450DS but after test driving it noticed a whine under the hood at approx 60 mph.  Backed off to 50, no whine.  Not sure I like this, and want to know if anyone else has experienced something similar.

Thanks very much,

What engine, what brand chassis?

Possible alternator bearing, it will whine when  ready to expire.

If you only hear it at speed, I would think it is wheel/tire or tranny related.

If the rig is good otherwise invest a couple of hundred bucks and take it to a good mechanic for diagnosis. NOT AN RV dealer
Have the mechanic get a sample of both the tranny oil and engine oil and send to blackstone oil

Another, very common source for a whine noise is any of the bearings on the serpentine belt accessory drive. I bought a kit that included everything from Rockauto for about $60. Regardless, it does not sound to me like it is a fatal or even deal breaking problem. I thought the noise mine made was the transmission at first. But if it was something in the transmission, the noise would be persistent and louder under throttle. Not to mention it'd be putting flakes of metal in the fluid. Personally, I'd try to diagnose the noise myself before paying a mechanic to look at it. OTOH, if you can find the right mechanic, it could be money well spent. Just because someone fixes things for a living doesn't mean a correct diagnosis.

Have you discussed the noise with the seller?

I guess I am lucky I have a mechanic in Syracuse and in Casa Grande that so far have never given me an incorrect diagnosis and always fixed the problem the first time

Ditto this. an independant RV mechanic, or even a Truck mechanic to review the chassis and Engine/power train for you can save you big bucks

YOU ARE SO SPECIAL!!

YOU ARE SO SPECIAL!!

No I do my due diligence before choosing  a mechanic.
In Syracuse I go to a place that maintains straight trucks  and greyhound buses so they deal with my chassis and motor day in and day out.
In Arizona my mechanic is a race car driver as a hobby and races 454 engine.
Money well spent if you find the right people to do the work you cannot
