I Recently bought a 99' Mustang 35th Anniversary. It was brought down to Florida from Ohio. Currently its in great condition and has no problems but whenever I drive it, it has a loudness of something spinning. I don't really know what it is or have any idea. I bought a Flowmaster Exhaust Kit, and I know it can't be that, because its more directed towards under the hood. I don't know, can someone give me some help/advice on what it may be? thanks

 

what do you mean somthing spinning, can you be more specific

 

Yea, that's like someone calling a shop and asking what a clunking noise is. Better to have more info.

 

for real.

what does he mean by a spinning noise?
belt loose?

 

Could be Alternator. P/S pump, A/C compressor, Water pump, Idler, Or even a vacuum leak. Just to many things....need input!!

 

ok, its a loud deep whining noise that varies between speeds. it doesnt do it at idle, only moving. i don't know how specific i can get

 

Those kinds of noises are really hard to diagnose without being there. But it kinda sounds like an accessory. Try spraying JUST A BIT of WD40 in each one..directed at the bearing. ONE AT A TIME. If the noise goes away..you found it. My suspicions are probably the belt idler or tensioner. Try those first. BUT..only use the SMALLEST amount of WD40. If you get it on the belt, you could induce a belt slip. If all else fails...take it to a local shop to identify it. I know..I hate taking mine in too. I'd rather do all the work myself.

 

hey, i fixed the noise it was my wheel bearings. thanks for the help tho guys and i didnt need a mechanic to do it for me =P
